Protein attributes

Sequence length	552 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Catalyzes the interconversion between glucose-6-phosphate and alpha-glucose-1-phosphate. This is the first 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	Alpha-D-glucose 1-phosphate = alpha-D-glucose 6-phosphate.
Cofactor	Binds 1 magnesium ion per subunit By similarity.
Pathway	Glycolipid metabolism; diglucosyl-diacylglycerol biosynthesis.
Sequence similarities	Belongs to the phosphohexose mutase family.
