Organism

Staphylococcus aureus (strain USA300) [Complete proteome] [HAMAP]

Taxonomic identifier

367830 [NCBI]

Taxonomic lineage

Bacteria › Firmicutes › Bacillales › Staphylococcus

Protein attributes

Sequence length	288 AA.
Sequence status	Complete.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	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.
Catalytic activity	UTP + alpha-D-glucose 1-phosphate = diphosphate + UDP-glucose.
Pathway	Glycolipid metabolism; diglucosyl-diacylglycerol biosynthesis.
Sequence similarities	Belongs to the UDPGP type 2 family.
