CC   -!- FUNCTION: Catalyzes the interconversion between glucose-6-phosphate and
CC       alpha-glucose-1-phosphate. This is the first step in the biosynthesis
CC       of diglucosyl-diacylglycerol (Glc2-DAG), i.e. the predominant
CC       glycolipid found in the S.aureus membrane, which is also used as a
CC       membrane anchor for lipoteichoic acid (LTA) (By similarity).
CC       {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=alpha-D-glucose 1-phosphate = alpha-D-glucose 6-phosphate;
CC         Xref=Rhea:RHEA:23536, ChEBI:CHEBI:58225, ChEBI:CHEBI:58601;
CC         EC=5.4.2.2;
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC       Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000250};
CC   -!- PATHWAY: Glycolipid metabolism; diglucosyl-diacylglycerol biosynthesis.
CC   -!- SIMILARITY: Belongs to the phosphohexose mutase family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=BAB58653.1; Type=Erroneous initiation; Evidence={ECO:0000305};
