Biosynthesis of UDP-N,N′-diacetylbacillosamine in Acinetobacter baumannii: Biochemical characterization and correlation to existing pathways

- The A. baumannii enzymes WeeK, J, and I produce UDP-diNAcBac.
- A. baumannii UDP-diNAcBac pathway enzymes are kinetically characterized.
- UDP-diNAcBac enzymes exhibit surprising diversity in N- and O-linked glycosylation.
- The terminal acetyltransferase may promote flux through the UDP-diNAcBac pathway.
