metabolism | cytokinins are important adenine-base phytohormones which promote cell division and their biosynthesis has two pathways depending on different substrates. The first pathway begins with the transfer of isopentenyl group from dimethylallyl diphosphate to the N6-amino group of AMP, ADP or ATP by adenylate isopentenyltransferase, AIPT | Humulus lupulus |
physiological function | the isopentenyltransferase reaction is the key rate-limiting step in cytokinin biosynthesis that transfers the isopentenyl group from dimethylallyl diphosphate to the N6-amino group of adenine | Humulus lupulus |
