CC   -!- FUNCTION: Catalyzes the formation of UDP-glucose from glucose-1-
CC       phosphate and UTP. This is an intermediate step in the biosynthesis of
CC       diglucosyl-diacylglycerol (Glc2-DAG), i.e. the predominant glycolipid
CC       found in B.subtilis membrane, which is also used as a membrane anchor
CC       for lipoteichoic acid (LTA). Has a role in the biosynthesis of all
CC       phosphate-containing envelope polymers, since UDP-glucose serves as a
CC       glucosyl donor not only for the biosynthesis of LTA but also for wall
CC       teichoic acids (WTAs). Is required for biofilm formation. This is
CC       likely due to another role of UDP-glucose, which might also act as a
CC       metabolic signal regulating biofilm formation or may be involved in
CC       some unknown biosynthetic pathway essential for biofilm formation, e.g.
CC       the synthesis of an exopolysaccharide. {ECO:0000269|PubMed:15640167,
CC       ECO:0000269|PubMed:2846750, ECO:0000269|PubMed:8126437,
CC       ECO:0000269|PubMed:8320212}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=alpha-D-glucose 1-phosphate + H(+) + UTP = diphosphate + UDP-
CC         alpha-D-glucose; Xref=Rhea:RHEA:19889, ChEBI:CHEBI:15378,

CC         Evidence={ECO:0000269|PubMed:33556370};
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       Kinetic parameters:
CC         KM=45.6 uM for glucose-1-phosphate {ECO:0000269|PubMed:33556370};
CC         KM=49.5 uM for UTP {ECO:0000269|PubMed:33556370};
CC         Note=kcat is 1.06 sec(-1) with glucose-1-phosphate as substrate. kcat
CC         is 1.04 sec(-1) with UTP as substrate. {ECO:0000269|PubMed:33556370};
CC   -!- PATHWAY: Glycolipid metabolism; diglucosyl-diacylglycerol biosynthesis.
CC       {ECO:0000269|PubMed:15640167}.
CC   -!- SUBUNIT: Interacts with FloT. {ECO:0000269|PubMed:23651456}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:23651456};
CC       Peripheral membrane protein {ECO:0000305}. Membrane raft
CC       {ECO:0000269|PubMed:23651456}; Peripheral membrane protein.
CC       Note=Present in detergent-resistant membrane (DRM) fractions that may
CC       be equivalent to eukaryotic membrane rafts; these rafts include
CC       proteins involved in signaling, molecule trafficking and protein
CC       secretion. {ECO:0000269|PubMed:23651456}.
CC   -!- INDUCTION: By heat shock, salt stress, oxidative stress, glucose
CC       limitation and oxygen limitation. Expressed under control of the sigma-
CC       B transcription factor. {ECO:0000269|PubMed:8320212}.
CC   -!- DISRUPTION PHENOTYPE: Under aerobic growth condition, deletion mutants
CC       display morphological defects and the cells are curled and show some
CC       bulges (PubMed:33556370). No aberrant morphology is observed for the
CC       deletion mutants under anaerobic growth conditions (PubMed:33556370).
CC       {ECO:0000269|PubMed:33556370}.
CC   -!- MISCELLANEOUS: GtaB is the main UGPase enzyme producing UDP-glucose
CC       under both aerobic and anaerobic fermentative growth conditions
CC       (PubMed:33556370). YngB augments UDP-glucose production under anaerobic
CC       growth conditions (PubMed:33556370). {ECO:0000269|PubMed:33556370}.
CC   -!- SIMILARITY: Belongs to the UDPGP type 2 family. {ECO:0000305}.
