title: Transferases of O-antigen biosynthesis in Salmonella enterica: dideoxyhexosyltransferases of groups B and C2 and acetyltransferase of group C2.
abstract: The O antigen is a polymer of oligosaccharide units. O antigens differ in their sugar composition and glycosidic linkages, and genes responsible for O-antigen-specific biosynthesis are grouped in the rfb gene cluster. In this study, we identified two abequosyltransferase genes and an acetyltransferase gene in Salmonella enterica groups B and C2 by in vitro assay and identified paratosyl-, tyvelosyl-, and abequosyltransferase genes from S. enterica groups A and D and Yersinia pseudotuberculosis serovar IIA, respectively, by comparison.
