The role of FAD cofactor of cytokinin oxidase/dehydrogenase in the mechanism of cytokinin breakdown (GP522/08/P113)

Cytokinins are plant hormones regulating many aspects of plant development. FAD-containing cytokinin oxidase/ dehydrogenase (CKO) catalyzes the oxidative breakdown of isoprenoid cytokinins. Covalent linkage of FAD ...

Isolation and identification of physiological electron acceptor of plant cytokinin dehydrogenase and interaction with low molecular mass compounds (GA522/05/0448)

Cytokinin dehydrogenase (CKX) degrades plant hormones cytokinins by oxidative cleavage of their side chain. Compounds of quinone nature are the likely electron and in a consequence can differ in mechanism of catalytic degra...
