RL J. Bacteriol. 194:2646-2657(2012).
CC -!- FUNCTION: Is the initiating enzyme for colanic acid (CA) synthesis.
CC Catalyzes the transfer of the glucose-1-phosphate moiety from UDP-Glc
CC onto the carrier lipid undecaprenyl phosphate (C55-P), forming a
CC phosphoanhydride bond yielding to glucosyl-pyrophosphoryl-undecaprenol
CC (Glc-PP-C55). Also possesses a weak galactose-1-P transferase activity.
CC {ECO:0000269|PubMed:22408159}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=di-trans,octa-cis-undecaprenyl phosphate + UDP-alpha-D-glucose
CC = alpha-D-glucosyl di-trans,octa-cis-undecaprenyl diphosphate + UMP;
CC Xref=Rhea:RHEA:28126, ChEBI:CHEBI:57865, ChEBI:CHEBI:58885,
CC ChEBI:CHEBI:60392, ChEBI:CHEBI:61254; EC=2.7.8.31;
CC Evidence={ECO:0000269|PubMed:22408159};
CC -!- PATHWAY: Exopolysaccharide biosynthesis; colanic acid biosynthesis.
CC {ECO:0000269|PubMed:22408159}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane
CC {ECO:0000269|PubMed:22408159}; Multi-pass membrane protein
CC {ECO:0000269|PubMed:22408159}.
CC -!- DISRUPTION PHENOTYPE: Cells lacking this gene show a non-mucoid
CC phenotype. {ECO:0000269|PubMed:22408159}.
CC -!- MISCELLANEOUS: Complements holdfast synthesis in the C.crescentus
CC mutant lacking hfsE, pssY and pssZ genes. Can also partially complement
CC the O-antigen defect in the S.typhimurium wbaP deletion strain
CC (PubMed:22408159). {ECO:0000305|PubMed:22408159}.
CC -!- SIMILARITY: Belongs to the bacterial sugar transferase family.
CC {ECO:0000305}.
