Anthocyanidin sambubioside biosynthesis is a pathway by which anthocyanins (plant pigments) become sambubiosides, diglucosides containing an attached xylose on the 2''-O-position of the 3-O-glucose moiety of anthocyanidins. First, anthocyanidin 3-O-glucoside 2'''-O-xylosyltransferase uses UDP to convert delphinidin 3-glucoside into delphinidin 3-sambubioside, cyanidin 3-glucoside into cyanidin 3-sambubioside, and pelargonidin 3-glucoside into pelargonidin-3-sambubioside. Second, the predicted enzyme anthocyanin 3-O-sambubioside 5-O-glucosyltransferase (coloured orange) is theorized to use UDP to convert cyanidin 3-sambubioside into cyanidin 3-sambubioside 5-glucoside and pelargonidin-3-sambubioside into pelargonidin 3-sambubioside-5-glucoside.
