CC   -!- FUNCTION: Involved in the biosynthesis of amylovoran, which functions
CC       as a virulence factor. May function as a glycosyl transferase which
CC       transfers galactose from UDP-galactose to a lipid-linked amylovoran-
CC       subunit precursor.
CC   -!- PATHWAY: Glycan metabolism; exopolysaccharide biosynthesis.
CC   -!- SIMILARITY: Belongs to the glycosyltransferase 2 family. {ECO:0000305}.
