New pneumococcal serotype 20C is a WciG O-acetyltransferase deficient variant of canonical serotype 20B by Jigui Yu, Neil Ravenscroft, Peter Davey, Roshan Liyanage, Oliver Lorenz, Michelle M. Kuttel, Stephanie W. Lo, Feroze A. Ganaie, Moon H. Nahm

“…ABSTRACT The polysaccharide (PS) capsule of Streptococcus pneumoniae (pneumococcus) is the immunodominant surface structure that shields the bacteria from the host immune system. Since the capsule is the primary target of currently available pneumococcal vaccines, anti-capsular antibodies are highly protective but serotype-specific. …”

Reinvestigation into the role of lipopolysaccharide Glycosyltransferases in Helicobacter pylori protein glycosylation by Hong Li, Xiaoqiong Tang, Tiandi Yang, Tingting Liao, Aleksandra W. Debowski, Tiankuo Yang, Yalin Shen, Hans-Olof Nilsson, Stuart M. Haslam, Barbara Mulloy, Anne Dell, Keith A. Stubbs, Wolfgang Fischer, Rainer Haas, Hong Tang, Barry J. Marshall, Mohammed Benghezal

“…As LPS is a unique component of virtually all Gram-negative bacteria, our data suggest that when observing protein electrophoretic mobility shifts between wild-type and LPS mutant strains or between subcellular fractionation samples, the influence of LPS on protein electrophoretic migration should be considered first, rather than interpreting it as potential protein glycosylation that is dependent upon LPS biosynthetic pathway.…”
