PLANT CYTOKININ DEHYDROGENASE IN COMPLEX WITH ISOPENTENYLADENINE
Overview
Cytokinins form a diverse class of compounds that are essential for plant, growth. Cytokinin dehydrogenase has a major role in the control of the, levels of these plant hormones by catalysing their irreversible oxidation., The crystal structure of Zea mays cytokinin dehydrogenase displays the, same two-domain topology of the flavoenzymes of the vanillyl-alcohol, oxidase family but its active site cannot be related to that of any other, family member. The X-ray analysis reveals a bipartite architecture of the, catalytic centre, which consists of a funnel-shaped region on the protein, surface and an internal cavity lined by the flavin ring. A pore with, diameter of about 4A connects the two active-site regions. Snapshots of, two critical steps along the reaction cycle were obtained through ... [(full description)]
