UTP--glucose-1-phosphate uridylyltransferase YngB

UniProtKB accession:  O31822

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the formation of UDP-glucose from glucose-1-phosphate and UTP (PubMed:33556370). This is an intermediate step in the biosynthesis of diglucosyl-diacylglycerol (Glc2-DAG), i.e. the predominant glycolipid found in B.subtilis membrane, which is also used as a membrane anchor for lipoteichoic acid (LTA) (PubMed:33556370). YngB contributes to wall teichoic acid (WTA) glucosylation and glycolipid formation under anaerobic fermentative growth conditions (PubMed:33556370). Might also enter other glycosylation pathways, leading to the decorating of other cell envelope components with glucose residues under anaerobic or other growth conditions (PubMed:33556370).
