CC   -!- FUNCTION: Catalyzes the acylation of glycosyl-4,4'-
CC       diaponeurosporenoate, i.e. the esterification of glucose at the C6''
CC       position with the carboxyl group of the C(15) fatty acid 12-
CC       methyltetradecanoic acid, to yield staphyloxanthin. This is the last
CC       step in the biosynthesis of this orange pigment, present in most
CC       staphylococci strains (By similarity). {ECO:0000250}.
CC   -!- PATHWAY: Carotenoid biosynthesis; staphyloxanthin biosynthesis;
CC       staphyloxanthin from farnesyl diphosphate: step 5/5.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Single-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the acyltransferase CrtO family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=ABD22726.1; Type=Erroneous initiation; Evidence={ECO:0000305};
