Research Interest
My research fields include synchrotron X-ray protein crystallography, molecular biophysics, structural biology and proteomics. The major research interest is to study crystal structure and functional relationship of various proteins, including protein-DNA/RNA interaction, virus, membrane proteins, enzymes, and other functional important proteins related to drug discovery by Protein Crystallography (PX), X-ray Absorption Fine Structure (XAFS), Circular Dichroism (CD) and Small Angle X-ray Scattering (SAXS) using synchrotron X-rays from NSRRC and SPring-8.
Some primary targets include the important proteins and metalloproteins of sulphate-reducing bacteria to understand the life process mechanisms in anaerobic and aerobic environment; the proteins involved rice seed germination and coleoptile elongation; the membrane proteins account for the electron transfer chain, oxygen defencing system and drug targets.
In addition, many collaborative projects with domestic and international research institutes and universities have been carried out to study a number of proteins involved in diseases, medial application, drug design, venom toxicity, viral disease, catalysis, metabolism, etc. Another interest is to investigate the methodology for resolving the phase ambiguity of single-wavelength anomalous dispersion (SAD), which applies to obtain the correct phases routinely and efficiently for structure determination of macromolecules.
