Brief of Researches

Our research direction mainly uses the techniques of x-ray crystallography to resolve 3 dimensional structures of macromolecules, including protein, DNA and RNA. We try to interpret the relationship on structure, function, molecular evolution and reveal biological information. The aims are to molecular mechanism in life. Our recent research topics of my lab are:

Bioenergy: Structural and functional analyses of cellulose synthases from Bambusa oldhamii (BoCesAs)

Plant cells are divided by cell walls which are composed of cellulose, hemicellulose, pectin and secondary metabolites. Up to 50% of cell wall substance is cellulose which is the most abundant biomass in the world. Cellulose synthase complex (CSC) located at the plasma membrane and cellulose synthases (CesAs) are the catalytic center. CesAs can synthesize glucan chain while cellulose synthase complex accumulates cellulose microfibril into plant cell wall. Bamboo is the most fast growing plants in the world. Its growth can reach 25 cm per day in suitable season. The fast growing would be accompanied by fast synthesis of cellulose. In this proposal, the cellulose synthases from Bambusa oldhamii (BoCesAs) will be analyzed by protein-protein interaction and protein structure approaches. 6 out of 10 cellulose synthases were expressed by yeast expression system, cultured in fermenter, purified by affinity column and monitored the oligomeric state of BoCesA protein by size-exclusion chromatog raphy. The molecular composition of cellulose synthase complexes will be individually in assembling and reconstructing from different cellulose synthases by protein-protein interaction and structure approaches.

Epigenetics regulatory proteins: Biochemical and biophysical study of plant histone deacetylases (HDAs)

Histone deacetylases (HDAs) involves in regulating plant growth, development and stress responses by relative gene expression. HDAs remove acetyl groups of histone to increase high-affinity interaction between histones and DNA. It results in chromatin condensation and then suppress gene expression. In Arabidopsis , 18 HDAs can be separated into 3 families: RPD3/HDA1-like family, HD2 family and Sirtuin family. The RPD3/HDA1-like family consists of the most members in eukaryotic cells and it can be further classified into 3 classes. In this project, we use an overexpression system of E. coli to express recombinant protein of class II histone deacetylase, including HDA5, HDA15 and HDA18. In preliminary study, enzyme activity and oligomerizaion of HDAs will be affected by its N-terminus or C-terminus The detailed molecular mechanism is under investigation. Recently, Epigenetics has become a popular research area. Lots of proteins would be interacted with HDAs to regulate transcription. We aim to resolve crystal structures of HDAs. In addition, the complex structures of HDAs with its interacting proteins, such as transcription factors and post-translational modification proteins, are also our future research direction to reveal their co-regulation role in gene expression. It is an important breakthrough in molecular regulation for Epigenetics research.

Drug design and development: Structure based inhibitors development of MutT Homolog 1 (MTH1)

MutT Homolog 1 (MTH1) has been proved that can hydrolyze oxidized deoxy-ribonleoside triphosphate (dNTP) in DNA repair. It can prevent highly wrong nucleotide to incorporate into DNA in DNA replication. In cancer cell, amount of reactive oxygen species can cause lots of oxidized dNTP. MTH1 could eliminate oxidized dNTP and prevent cancer cell to enter apoptosis. MTH1 is not required in normal, but its expression is higher in cancer cells. Therefore, inhibition of MTH1 activity was considered to be anti-cancer cell target. In this research, we screened 2,313 drugs of fragment based compound library. 4 potential MTH1 inhibitors using ultra high throughput drug system were found. We determined crystal structures, inhibitor ability, and cell viability. Based on these structures of 4 fragment based inhibitors and MTH1, new compounds will be modified and to test inhibitor ability for MTH1. Furthermore, new compounds could be used in animal system experiment.

Previous study are summarzied below,

Structural basis of FIN219-FIP1 complex

Light regulated JA signalingFIN219 (Far-red insensitive 219, AtGH3.11) is jasmonate synthetase to conjugate jasmonate to amino acids for jasmonate signaling pathway in plants. Previous study has been indicated that FIN219 involved in phytochrome A-mediated far-red (FR) light signaling and interact with FIP1 (FIN219-interacting protein 1) as known as GST tau20 in Arabidopsis. In 2012, crystal structure of FIN219 has shown carboxyl-terminal region is highly flexible to regulate the enzyme activity. However, it still unknown to explain the interaction of FIN219 and FIP1 in enzyme activity and complex structure. We report the crystal structures of FIN219-FIP1 complex and identify three substrates binding site. FIN219 hinge-loop linked N- and C-terminal region reveals distinct architecture from open-form of PBS3 (AtGH3.12) and close-form of JAR1, and FIN219 S447, K456 and R499 generate salt bridge interactions with FIP1 A184, R188 and D201. The C-terminal helix 528-537 inserts into FIN219 N -terminal active site and pushes ATP toward JA, and K557 provides electrostatic interaction with γ-phosphate of ATP. QCM assay also shows that jasmonic acid (JA) has a dominant binding order for catalysis, and FIN219-FIP1 complex reveals 2.3-fold Kcat and 2-fold Vmax constant higher than FIN219 only. Our results establish FIP1 actually enhance FIN219 enzymatic activity by interacting to C-terminal domain and further conformational changes. Proc. Natl. Acad. Sci.

Crystal structure of group 2 phytocystatin

CeCPI-Papain complex Phytoystatins are specific inhibitors of cysteine proteases. The possible roles are proposed for phytocystatins: (i) they could act as regulators of proteolysis during seed maturation and germination; (ii) they served in plant defense by inhibiting exogenous proteases from insect pests, nematodes and fungi; (iii) they are thought to be a regulated factor under environmental stress. Based on the molecular sizes, the phytocystatin can be divided to three groups: (1) 12~16kDa; (2) ~23kDa; ( 3) ~80kDa. A group 2 phytocystatin from taro will be purified and crystallized for X-ray crystallography. The full length (FL), Nt and Ct segments of gene of tarocystatin were expressed in E. coli. In previous experiment, FL and Nt exhibited anti-papain activity, but Ct peptide could enhance papain activity in kinetic assay. Therefore, we would like to solve the crystal structure of tarocystatin in group-2 using molecular replacement since the NMR structure of oryzacystatin in group -1 has been solved. We also plan to prepare the complex structure of cystatin-papain for observing the relationship between papain and cystatin, or papain and Ct. We propose that the results will have some explanations in inhibition activity and evolutionary role of group- 2 phytocystatin. Planta. (2011) 234(2):243-54. Epub on Mar 17, 2011

Structural and functional analyses of TLP18.3 idenfied its phosphatase activity

TLP18.3AtTLP18.3 is an 18.3 kDa thylakoid lumen protein with 285 amino acids. Previous studies indicated that the AtTLP18.3 protein is an auxiliary protein of photosystem II (PSII) repair cycle. In order to clarify the possible molecular function of the AtTLP18 .3 protein, the crystal structures of the truncated AtTLP18.3 without targeting signal and TMH were resolved. Since there is no any methionine residue in the truncated AtTLP18.3 protein, L128M and L159M were introduced for MAD method by site-directed mutagenesis. The crystals of native and double mutated AtTLP18.3 shows isomorphous in space group P212121 with unit-cell parameters a = 46.9, b = 49.8, c =76.7?A, α=β=γ=90°. Finally, the structure of mutant was resolved at a resolution 2.6?A using single-wavelength anomalous dispersion (SAD) method, and the native structure was resolved at 1.6?A resolution. For further structural comparison, the native structure of truncates AtTLP18.3 was submitted to the DALI and CATH database to se arch similar folding of protein with known function. The results showed that the structure of AtTLP18.3 resembled to various inorganic pyrophosphatase. The enzymatic activity of AtTLP18.3 was further identified by pNPP phosphatase assay. Therefore, we proposed that the function of AtTLP18. 3 will act as phosphatase to remove the phosphate group from damage protein for repair cycle. Plant Physiol.

Crystal structure of T-domain of ColE7

ColE7 is an operon, which classified as one of the Escherichia coli secretary toxins, is released under stress conditions (UV radiation, starvation, antibiotic treat) to kill other related bacteria. The operon contained three genes: (1) ColE7: N-terminal translocation domain (T-domain), Middle Receptor binding domain (R-domain) and C-terminal nuclease domain (Toxicity domain). (2) ImE7: an immunity protein is co-expressed with ColE7 to inhibit the nuclease activity of ColE7 in host cells. (3)Lys: a protein to penetrate the membrane of host cell for helping ColE7 to secrete into environment. The domains of ColE7 play different roles for binding and killing the target cell. We focus on the crystal structure of T domain to demonstrate the function from structure comparison, functional assay and distribution on electro-potential surface.
