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 B.subtilis membrane, which is also used as a membrane anchor for lipoteichoic acid (LTA). Has a role in the biosynthesis of all phosphate-containing envelope polymers, since UDP-glucose serves as a glucosyl donor not only for the biosynthesis of LTA but also for wall teichoic acids (WTAs). Is required for biofilm formation. This is likely due to another role of UDP-glucose, which might also act as a metabolic signal regulating biofilm formation or may be involved in some unknown biosynthetic pathway essential for biofilm formation, e.g. the synthesis of an exopolysaccharide. Ref.1 Ref.2 Ref.5 Ref.6
Catalytic activity	UTP + alpha-D-glucose 1-phosphate = diphosphate + UDP-glucose.
Pathway	Glycolipid metabolism; diglucosyl-diacylglycerol biosynthesis. Ref.6
Induction	By heat shock, salt stress, oxidative stress, glucose limitation and oxygen limitation. Expressed under control of the sigma-B transcription factor. Ref.1
Sequence similarities	Belongs to the UDPGP type 2 family.
