Pathology & Biotechi

Biotechnological usei

A one-pot system for efficient enzymatic production of a wide range of glucosides couples the activities of two recombinant enzymes, UDP-glucose: curcumin glucosyltransferase from Catharanthus roseus (CaUGT2) and sucrose synthase from Arabidopsis thaliana (AtSUS1). UDP, a product inhibitor of UDP-glucosyltransferase, was removed from the system and used for regeneration of UDP-glucose by the second enzyme, AtSUS1. The productivity was increased several-fold and UDP-glucose initially added to the reaction mixture could be reduced to one-tenth of the normal level.1 Publication
