Fin219-FIP1 complex structure and function analysis
FIN219 (Far-red insensitive 219), also known as JAR1 (Jasmonate Resistant 1), is a protein composed of 575 amino acids, belonging to the Arabidopsis thaliana GH3 protein family. This protein in plants regulates the constancy of hormones in plants by combining plant hormones and amino acids such as indole-3-acetic acid (IAA) and jasmonic acid (JA) , Which in turn affects the growth and development of plants and the ability to resist pests and diseases. The functions of FIN219 can be divided into the following two directions:
(i) Related to Photomorphogenesis Photomorphogenesis is jointly regulated by photosensitizers that absorb red and far-red light and cryptochromes that absorb UV-A and blue light. Under far-red light irradiation, the fin219 mutant seedlings of Arabidopsis thaliana have an elongated hypocotyl phenotype and act as an extragenic suppressor of cop1 (Hsieh et al., 2000). In addition, the GST (glutathione S-transferases) protein gene fip1 (FIN219-interacting protein 1), the protein produced by it has been confirmed to interact with the C-terminus of FIN219 (Hsieh et al., 2007)
(ii) Regarding the regulation of plant hormones Jasmonic acid plays an important message transmission role in plants, which involves the transmission pathways of growth and development, resistance to diseases and insect pests and plant injuries. However, the understanding of jasmonic acid at the molecular level is very limited. At present, it is known that there are many small molecules that connect jasmonic acid and amino acid in plants, such as JA-Leu, JA-Val and JA-Phe, which are derived from JAR1. Catalyzes the joining of jasmonic acid and amino acids, of which JA and Ile have the highest affinity. Taking the Arabidopsis mutant strain jar1-1 of JAR1, adding JA-Ile in the medium can inhibit the elongation of the hypocotyl of seedlings, which is consistent with the wild type of JAR1. The JAZ (jasmonate ZIM-domain) protein family is considered to be an important key to regulating the transmission of jasmonate. JAZ1 can usually inhibit the transcription of jasmonate-responsive genes, but after treatment with jasmonate, it will cause the Degradation in the nucleus promotes the expression of genes related to the jasmonic acid reaction. The degradation mechanism is through SCFCOI1 (Skp/Cullin/F-box complex), a ubiquitin ligase (E3 ubiquitin ligase), which completes the interaction between proteins . The small molecule JA-Ile that promotes the interaction between Col1 and JAZ1 is the small molecule JA-Ile, which shows that JAR1 may be an important hub in regulating the delivery of jasmonic acid and the quality of related proteins. The results of this research were published in Proc. Natl. Acad. Sci. USA 114:E1815-E1824. Epub Feb 21, 2017
Previously completed research topics
Protein structure and function is an area that is highly valued in the post-genome era. Structural and functional analysis provides a three-dimensional view of the molecular level.
We use the technology of protein crystallography to analyze the three-dimensional structure of biological macromolecules (including DNA, RNA and protein), and to explore the structure, function, molecular evolution and related biological information.
Our current research directions are:
1. Biomass energy:
Analysis of protein structure and function of green bamboo cellulose synthase The plant cell wall is mainly composed of cellulose, hemicellulose, pectin, and secondary metabolites. Cellulose accounts for more than 50% of the cell wall composition and is the most abundant biomass on earth. The enzyme responsible for the production of cellulose in plant cells is the cellulose synthase complex (CSC), of which cellulose synthase (CesA) is the catalytic core and serves as the synthesis of long-chain sugars for the cellulose synthase complex Produce microfibril (microfibril), and further form plant cell wall. Bamboo is the fastest growing plant, with an average daily growth of up to 25 cm, indicating that its cellulose synthesis also needs to match its growth rate. This study analyzes the protein structure and biophysical properties of green bamboo cellulose synthases (Bambusa oldhamii Cellulose synthases, BoCesAs). There are 10 types of green bamboo cellulose synthase (BoCesA1~10). Currently, yeast expression system, fermented enzymes, has been used. The tank mass cultivation and rapid protein purification instrument successfully expressed BoCesA1, 2, 3, 4, 5 and 7 proteins, and subsequent development of enzyme activity analysis methods, protein crystal structure analysis and related biophysical research will be carried out successively. The ultimate goal is to analyze the structure of the green bamboo cellulose synthase complex to explore the molecular mechanism of plant cellulose synthesis.
2. Research on epigenetic regulatory proteins:
Biochemical and Biophysical Research on Plant Deacetylases HDAs Histone deacetylases (HDAs) are involved in the regulation of plant growth, development and the gene expression required for plant response to stress. The enzymatic activity of HDAs is to remove the acetyl group on histones and promote the formation of tight binding between histones and DNA. As a result, the chromatin will be concentrated and the genes located in this region cannot be expressed. There are 18 HDAs in Arabidopsis thaliana, which can be divided into three families: RPD3/HDA1-like family, HD2 family and Sirtuin family. Among them, RPD3/HDA1-like family has the most members and can be subdivided into three groups. This study is mainly aimed at The second group of HDA5, HDA15 and HDA18 were studied. Other HDAs will also continue to be studied. At present, we have constructed the active regions of the second group of deacetylases respectively, and performed activity analysis and comparison and protein structure analysis. Among them, the activity and polymerization form of HDA15 are affected by its N-terminal and C-terminal, which helps to understand its The molecular mechanism of action. Since epigenetic research has been very popular in recent years, and there are many proteins that interact with each other, this research topic will not only explore the structure of HDAs, but also focus on the binding proteins of related HDAs, such as transcription factors and post-translational modification proteins, etc. , To explore the ways of co-regulating gene expression. If the structure of these interacting proteins and HDAs can be resolved, it will be a major breakthrough for epigenetic research.
3. Drug design and development: MTH1 inhibitor structure and its inhibitory efficiency analysis
MutT Homolog 1 (MTH1) has been confirmed to have hydrolyzed and oxidized nucleotide triphosphates (dNTPs) to prevent the wrong nucleotide triphosphates (dNTPs) from being incorporated into DNA replication and causing gene mutations. In cancer cells, high levels of peroxide are easily produced, causing DNA damage. MTH1 can remove oxidized dNTPs to prevent cancer cells from entering the process of apoptosis. MTH1 is expressed in a small amount in normal cells, but in a large amount in cancer cells. Therefore, inhibiting the activity of MTH1 may be used as a drug to inhibit cancer cells and promote cancer cells to enter apoptosis. This study was developed in cooperation with the Department of Pharmacy. At the initial stage, more than 2,300 fragment based compound libraries were jointly screened. Using the ultra high throughput drug system of the Academia Sinica, 4 compounds were found to have MTH1 inhibitory ability. We analyzed The IC50 and enzyme kinetics of these four compounds, and the protein structure of three of them and MTH1 are solved. Based on the structure of these three compounds, new compounds will be further designed to analyze the inhibitory efficiency of MTH1 and the growth of cancer cells. The impact of these results will provide valuable drug design and development, and test the effectiveness of experiments in animal systems.

Ipomoelin-a sugar-binding protein induced by trauma and Jasmonate in sweet potato leaves
Lectin is a superfamily of a group of sugar-binding proteins in plants. When plants are subjected to biological adversity, such as herbivores gnawing and causing trauma, they will express this type of protein in large quantities. Therefore, they are regarded as plants suffering from animal taking. One of the defensive proteins produced during eating. Ipomoelin (IPO) is derived from sweet potato, and is abundantly expressed in leaves when sweet potato is infested by insects. After analysis, it can be classified as a group of glyco-binding proteins called Jacalin-related Lectins. This group is structurally composed of a single protein folded into a beta-prism monomer, and then further composed of four Tetramer. At present, it is known that this group of Jacalin-related Lectins have the characteristics of structural diversity, which means that this group of proteins consists of similar triangular-shaped monomers, which can form different forms of dimers, tetramers, and hexamers. (hexamer) and octomer, etc.
After analyzing the structure of IPO, it was found that it has an additional N-terminal structure that can form a tighter tetrad, which is not the same as the current tetrad formed in the Jacalin group, although they are all beta-triangular. It is composed of monomers, but the combination is very variable. This variability can provide useful information about protein-protein interaction. In addition, we also co-crystallized sugars such as methyl-alpha-D-mannose, methyl-alpha-D-glucose, and (sialic acid) sialic acid with IPO to obtain a complex structure. After comparing the binding modes of these sugars, we can Providing the specificity of IPO for carbohydrate binding will help the application of this type of carbohydrate binding protein in glycoprotein analysis.

Structural analysis of plant anti-insect and antibacterial protein-cysteine protease inhibitor
Tarocystatin is a kind of cysteine protease inhibitor, a protease inhibitor that is expressed in large quantities in taro. The current research on this type of protease inhibitor mainly lies in the analysis of the inhibitory activity of its corresponding protease (such as papain). Since fungi, nematodes, and insects ingest plants, they need the action of cysteine proteases. Therefore, plants use a large number of protease inhibitors to reduce or avoid the invasion of these organisms. We co-crystallized Tarocystatin and papain, and analyzed the structure of this complex by X-ray crystal diffraction technology, and established that its protease inhibition mode is similar to the binding mode in animals, showing that this type of cysteine protease inhibits during the evolution process. The agent is based on a similar structure to achieve the purpose of plant insect resistance. In addition, we also completed the analysis of the inhibitory ability of tarocystatin by the analysis of inhibitory activity, and then we will target the C-terminal structure.
Tarocystatin is a family of plant cysteine protease inhibitors (Phytocystatins). This family can be divided into three groups according to molecular weight: the first group has the smallest molecular weight, about 100 amino acids have a single CY domain, represented by rice OC-1. Its protein structure was solved by NMR method in 2000 and published in Biochemistry by Nagata et al. The second group has a larger molecular weight, about 205-250 amino acids, represented by tarocystatin, which can be divided into two domains, one The N-terminus, which is similar to the first group sequence, is the main inhibitory region. The other C-terminus extension region may have a structure similar to CY domain without inhibitory function. The third group is a protease inhibitor composed of repeated CY domains, with about 750 amino acids and 6 to 8 CY domains, represented by Potato PMC. Its structure was published by Nissen et al. in this year's Plant cell ( 2009).
Here our research focuses on the second group of tarocystatin. This feature is that this protein has a C-terminal CY-like domain and does not have the function of an inhibitor. Therefore, we tried to co-crystallize tarocystatin and papain, hoping to solve the problem. The full-length crystal structure of Tarocystatin and papain will be developed. This will be the first complex structure of Phytocystatins and papain, and it will also provide important molecular evolution information. Due to the difficulty of co-crystallization with active papain, according to previous literature, under many conditions, only the structure of papain can be resolved. Even so, we still try to test its composite structure.
After two years of continuous protein expression, purification, and co-crystallization conditions, the complex crystals were finally grown under a specific crystallization condition for one month. After synchrotron radiation diffraction analysis, a complex structure with a resolution of 2.03 Å was obtained. Interestingly, only the N-terminal CY domain is combined with papain in a 1:1 manner, and the C-terminal structure cannot be observed. This phenomenon seems to mean that the C-terminal may be combined with papain first to increase its N Inhibition ability at the end. In addition, we also designed different fragments, such as full length, N-terminal and C-terminal and GST binding or not, and tested the binding ability of N-terminal and C-terminal. The analysis by Glutaraldehyde cross-linking and yeast two hybrid test showed that the majority of Tarycystatin N-terminal and C-terminal are separated; a small part can form intramolecular binding; in addition, some can form homodimer through the combination of N-terminal and N-terminal. Finally, we also tested the difference in its inhibitory ability. The results found that GST-FL has the best ability to inhibit papain, followed by GST-Nt and FL. Nt inhibition is the weakest here. In addition, GST-Ct can promote papaya. Enzyme activity capacity. This result indicates that the appearance of Ct is very important for improving the suppression ability. Planta.

Analysis of the structure and function of the stress-resistant protein TLP 18.3, which is abundantly expressed in chloroplasts, when plants are subjected to non-biological (water shortage) stress
There are very few research reports on TLP 18.3. In the knock out experiment, no obvious external phenotype appeared, indicating that it may have similar proteins in the chloroplast at the same time, performing similar effects, showing its importance. It is speculated that TLP18.3 may be involved in the photorepair of photosynthetic system II (PSII). Because the photosynthetic system is under long-term action, its D1 protein is easily damaged by light. At this time, peripheral proteins are needed to help remove damaged proteins. At that time, TLP 18.3 may perform this important task, but its molecular function is not clear! Therefore, this study is to use the correlation between structure and function, try to use X-ray crystal diffraction to study its structure, and use the structure Compare and find out its possible molecular functions.
Since TLP18.3 protein does not have methionine, many tests have been conducted for the expression, purification, and site-directed mutagenesis of this protein in the first two years, and the native TLP18.3 high-resolution diffraction data (resolution of 1.52Å) were obtained. , And use the TLP18.3 mutant (resolution 2.6Å) to obtain the phase angle by the single-wavelength unusual scattering method (SAD), and then use the modeling software and correction program to complete the protein structure analysis. After structural comparison, several similar structures have acid phospholytic enzyme activity. Therefore, it is speculated that this protein may have similar phospholytic enzyme activity. The activity analysis is further designed to perform sequence enzyme concentration, pH value, and temperature with substrate pNPP. , The experiment of removing bound ions shows that it does have the function of phospholytic enzyme activity. TLP18.3 has only a single Domain, belonging to the unknown family DUF477 (pfam). It has similar proteins in photosynthetic bacteria, algae, plants and prokaryotes. It is expected that this highly resolved protein structure will provide important information for this family. Structure and function information. Plant Physiol.
