WebFeb 1, 2006 · The gene prt is part of rfb cluster of genes and encodes for CDP paratose synthase which converts CDP‐4‐keto‐3,6‐dideoxyglucose to CDP paratose. This gene is present in serovar Typhi, Paratyphi A and few others. The fliC‐d gene is present in over 100 Salmonella serovars.

WebTyvelose epimerase catalyzes the last step in the biosynthesis of tyvelose by converting CDP-d-paratose to CDP-d-tyvelose. This unusual 3,6-dideoxyhexose occurs in the O-antigens of some types of Gram-negative bacteria. Here we describe the cloning, protein purification, and high-resolution x-ray crystallographic analysis of tyvelose epimerase ...
WebWbyM is only 21% identical to WbyA but is similar to several sugar transferases and is presumably the paratose transferase, since paratose is unique to IA and this is the only linkage specific to IA.
