Abstract

The proposal will use multi-disciplinary approaches to elucidate the biosynthesis of group II capsular polysaccharides in Escherichia coli. The specific aims are: First to identify the alpha-glycosyltransferase active site in the KfiC transferase which polymerises the K5 polysaccharide. KfiC is a rare example of a glycosyltransferase with both alpha and beta transferase activity. Such bifunctional glycosyltransferases have not been studied to date. Secondly to identify the roles of the KpsC and S proteins in the attachment of phosphatidyl-KDO to the reducing end of group II capsular polysaccharides. Finally to elucidate the protein/protein and protein/polysaccharide interactions in the assembly and function of the polysaccharide biosynthetic complex on the inner membrane. This study will reveal at the molecular level the biosynthesis of capsular polysaccharides in E. coli.
