Protein

UTP--glucose-1-phosphate uridylyltransferase

Gene

gtaB

Organism
Staphylococcus aureus (strain Mu50 / ATCC 700699)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the formation of UDP-glucose from glucose-1-phosphate and UTP. 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) (By similarity).By similarity

Catalytic activityi

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

Pathwayi: diglucosyl-diacylglycerol biosynthesis

This protein is involved in the pathway diglucosyl-diacylglycerol biosynthesis, which is part of Glycolipid metabolism.
