Isolation of Legume Glycosyltransferases and Active Site Mapping of the Phaseolus lunatus Zeatin O-glucosyltransferase ZOG1


O-Glycosides of the cytokinin zeatin are found in many plant tissues. They provide protection against degradative enzymes and may serve as cytokinin reserves. Two zeatin glycosyltransferase (GT) genes, an O-glucosyltransferase (ZOG1) from Phaseolus lunatus and an O-xylosyltransferase (ZOX1) from P. vulgaris, were previously isolated. Five novel bean and… (More)
