In Salmonella enterica, there is a great variety of O antigens, each consisting of a short oligosaccharide (the repeating unit) repeated many times. The O antigens differ in their sugar composition and glycosidic linkages. The genetic determinants of the O antigen are located in an rfb gene cluster, and some, including those of S. enterica O serogroups B, C2, and E1, have been cloned and sequenced. In this study of the glycosyltransferases which form the glycosidic linkages, we identify and characterize the four mannosyl and three rhamnosyl transferase genes of the three rfb gene clusters.
在肠炎沙门氏菌中,存在多种O抗原,每种O抗原都由一个短寡糖(重复单元)多次重复组成。O抗原在其糖组成和糖苷键方面存在差异。O抗原的遗传决定因素位于rfb基因簇中,其中一些,包括肠炎沙门氏菌O血清群B、C2和E1的那些,已经被克隆和测序。在这项关于形成糖苷键的糖基转移酶的研究中,我们鉴定并表征了三个rfb基因簇中的四个甘露糖基转移酶基因和三个鼠李糖基转移酶基因。
