Abstract
There are only sparse data on the enzymology of sugar chain synthesis in steroid glycoalkaloids. Earlier papers1,2 have described the ability of crude homogenates of Solanum laciniatum leaves or S. tuberosum tubers to glucosylate solasodine (an alkaloid of the spirosolane type) or solanidine (an alkaloid of the solanidane type), respectively, in the presence of UDP-glucose (UDPG1c). Recently, the glucosyltransferase present in S. tuberosum which catalyzes the formation of solanidine 3-O-monoglucoside (γ-onine) has been partly purified and characterized3-8.
