CC   -!- FUNCTION: Catalyzes the formation of UDP-glucose from glucose-1-
CC       phosphate and UTP. This is an intermediate step in the
CC       biosynthesis of diglucosyl-diacylglycerol (Glc2-DAG), i.e. the
CC       predominant glycolipid found in the S.aureus membrane, which is
CC       also used as a membrane anchor for lipoteichoic acid (LTA) (By
CC       similarity).
CC   -!- CATALYTIC ACTIVITY: UTP + alpha-D-glucose 1-phosphate =
CC       diphosphate + UDP-glucose.
CC   -!- PATHWAY: Glycolipid metabolism; diglucosyl-diacylglycerol
CC       biosynthesis.
CC   -!- SIMILARITY: Belongs to the UDPGP type 2 family.
