Chain-Length Regulation by WzzE Is Necessary for, but Genetically Separable From, Cyclic Enterobacterial Common Antigen Synthesis.

Molecular microbiology - 1 Aug 2026

Abstract excerpt

Enterobacterial common antigen (ECA) is a conserved glycan that supports intrinsic antibiotic resistance in Enterobacterales. ECA exists in outer membrane diacylglycerol-phosphate- and lipopolysaccharide-linked forms, and a cyclic periplasmic form (ECACYC). Intriguingly, ECACYC both affects the outer membrane permeability barrier and functions in regulation of diacylglycerol-phosphate-linked ECA. While the length...
