Natural Substrates/ Products (Substrates)

Natural Substrates Organism Comment (Nat. Sub.) Natural Products Comment (Nat. Pro.) Rev. Reac.
additional information Pisum sativum irreversible oxidative cleavage of the N6-side chain of cytokinins, products are adenine and side-chain derived aldehyde, results suggest that CKX is responsible for the changes in endogenous cytokinin pool in gibberellic acid-treated plants and most probably this enzyme represents an important link in gibberellic acid/cytokinin cross talk ?
