(2R,3R,4S,5S,6R)-2-(6-{[(2E)-4-hydroxy-3-methylbut-2-en-1-yl]amino}-7H-purin-7-yl)-6-(hydroxymethyl)oxane-3,4,5-triol
描述
Cis-zeatin-7-N-glucoside is an intermediate in cytokinins 7-N-glucoside biosynthesis. It is generated from cis-zeatin via the enzyme UDP glycosyltransferase.Several types of cytokinins conjugation exist which render cytokinins inactive: O-xylosylation, O-glucosylation, and N-glucosylation. When plants are subjected to high levels of cytokinin application, the major conjugate that forms is the 7-N-glucoside. Moreover, unlike O-glucosides, the glucosylation of which is reversible through the action of glucosidases, 7-N- and 9-N-glucosides are resistant to glucosidases. This, taken with N-glucosides accumulation in plant subjected to high doses of cytokinins, has led to the suggestion that N-glucosylation is involved in detoxification. [HMDB]
