Abstract
Sucrose and sucrose 6-phosphate synthetase were isolated from potato tubers, partially purified and their properties studied. The sucrose synthetase showed optimum activity at 45° and was inhibited competitively by ADP and some phenolic glucosides. The Ki′s for these inhibitors were determined. Mg2+ was found to activate this enzyme. Activity toward UDP-glucose or ADP-glucose formation was measured. The optimum conditions for sucrose and UDP-glucose formation were found to differ. The specificity for the glucosyl donor and acceptor were determined.This publication has 14 references indexed in Scilit:
