Characterization of PglJ, a Glycosyltransferase in the Campylobacter concisus N-Linked Protein Glycosylation Pathway that Expands Glycan Diversity.

ABSTRACT: The Campylobacter genus of Gram-negative bacteria is characterized by the expression of N-linked protein glycosylation (pgl) pathways. As Campylobacter concisus is an emerging human pathogen, a better understanding of the variation of the biosynthetic pathways across the genus is necessary to identify the relationships between protein glycosylation and disease. The pgl pathways of C. concisus strains have been reported to diverge from other Campylobacter in steps after the biosynthesis of N-acetylgalactosamine-α1,3-N,N'-diacetylbacillosamine-α-1-diphosphate undecaprenyl (GalNAc-diNAcBac-PP-Und), which is catalyzed by PglC and PglA, a phosphoglycosyltransferase (PGT) and a glycosyltransferase (GT), respectively. Here we characterize the PglJ GTs fro
