Involved in glycosylation steps downstream of mono-O-methyl-glycosyl-p-hydroxybenzoic acid derivative (p-HBAD I) and 2-O-methyl-rhamnosyl-phenolphthiocerol dimycocerosate (mycoside B) during the p-hydroxybenzoic acid derivatives (p-HBAD) and glycosylated phenolphthiocerol dimycocerosates (PGL) biosynthesis. Belongs to the glycosyltransferase 2 family.
