The primary in vivo steroidal alkaloid glucosyltransferase from potato

Transgenic plants expressing antisense Sgt2 under the transcriptional control of the granule bound starch synthase promoter showed an increase in α-solanine accumulation and a reduction in α-chaconine levels in tubers. Substrate preference for recombinant SGT2 demonstrated its primary activity as the UDP-glucose:solanidine glucosyl transferase.
