Protein

UTP--glucose-1-phosphate uridylyltransferase

Gene

gtaB

Organism
Staphylococcus aureus (strain NCTC 8325)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the formation of UDP-glucose from glucose-1-phosphate and UTP (Probable). This is an intermediate step in the biosynthesis of diglucosyl-diacylglycerol (Glc2-DAG), i.e. the predominant glycolipid found in the S.aureus membrane, which is also used as a membrane anchor for lipoteichoic acid (LTA).Curated1 Publication

Catalytic activityi

UTP + alpha-D-glucose 1-phosphate = diphosphate + UDP-glucose.
