Catalyzes the glycosylation of 4,4'-diaponeurosporenoate, i.e. the esterification of glucose at the C1'' position with the carboxyl group of 4,4'-diaponeurosporenic acid, to form glycosyl-4,4'-diaponeurosporenoate. This is a step in the biosynthesis of staphyloxanthin, an orange pigment present in most staphylococci strains. Carotenoid biosynthesis; staphyloxanthin biosynthesis; staphyloxanthin from farnesyl diphosphate: step 4/5. Belongs to the glycosyltransferase 2 family. CrtQ subfamily.
