  主要研究兴趣
1.     Legionella pneumophila, the causative agent of Legionnaires' disease, is  a Gram-negative facultative intracellular pathogen capable of multiplying in a  wide spectrum of eukaryotic cells. The pathogenicity of L.pneumophila is  entirely dependent upon its ability to replicate within host cell, a process  that requires the Dot/Icm type IV secretion system (T4SS). The Dot/Icm  transporter injects a large number of virulence factors into host cells and many  of these virulence factors benefit the bacterium by controlling host membrane  transport.
  Our research will focus on the structural and functional  characterization of some factors. Functional and crystallographic studies will  provide fundamental insights into the structural basis as well as the molecular  mechanism of these factors in host cells. The structural and functional  information will lay the foundation for the development of novel prevention and  therapeutic strategies against diseases caused by L. pneumophila and  possibly other infectious agents. It will also provide new tools and reagents  invaluable in the investigation of host processes.  

2.   Laccases are oxidoreductases that belong to the  multinuclear copper-containing oxidases. They are able to oxidize a wide range  of substrates, preferably phenolic compounds, which makes them suitable for  employment in the bioremediation of soil and water as well as in other  biotechnological applications. We use structure approaches, as well as  biochemical technique to address the details of laccase oxidation  mechanism.
