Function

function

Is likely the initiating enzyme for holdfast polysaccharide synthesis. Catalyzes the transfer of the glucose-1-phosphate moiety from UDP-Glc onto the carrier lipid undecaprenyl phosphate (C55-P), forming a phosphoanhydride bond yielding to glucosyl-pyrophosphoryl-undecaprenol (Glc-PP-C55). Also possesses a weak galactose-1-P transferase activity.

Miscellaneous

Complements colanic acid (CA) synthesis in the E.coli mutant lacking wcaJ. Can also partially complement the O-antigen defect in the S.typhimurium wbaP deletion strain (PubMed:22408159).
