CC   -!- FUNCTION: Catalyzes the glycosylation of 4,4'-diaponeurosporenoate,
CC       i.e. the esterification of glucose at the C1'' position with the
CC       carboxyl group of 4,4'-diaponeurosporenic acid, to form glycosyl-4,4'-
CC       diaponeurosporenoate. This is a step in the biosynthesis of
CC       staphyloxanthin, an orange pigment present in most staphylococci
CC       strains (By similarity). {ECO:0000250}.
CC   -!- PATHWAY: Carotenoid biosynthesis; staphyloxanthin biosynthesis;
CC       staphyloxanthin from farnesyl diphosphate: step 4/5.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the glycosyltransferase 2 family. CrtQ
CC       subfamily. {ECO:0000305}.
