RESEARCH SUMMARY

Dr. Xia devotes his research to the structure and function relationship of membrane proteins at atomic resolution. He determined the crystal structures of Complex III or cytochrome bc1 complex of respiratory and photosynthetic apparatus and elucidated mechanisms of its function and antibiotic resistance. These works form the foundation that guides rational drug design against Complex III of pathogenic organisms.

Recently, Dr. Xia has focused his attention to the structural mechanism of multidrug resistance mediated by membrane transporters. Structural revelation of these transporters promise a detailed understanding of how diverse drugs are pumped and how resistance might be reversed.
