Cytokinin dehydrogenase 1, FAD/cytokinin binding domain (IPR015345)

Short name: Cytokinin_DH_FAD/cytokin-bd

Overlapping homologous superfamilies

Domain relationships



This domain adopts an alpha+beta sandwich structure with an antiparallel beta-sheet, in a ferredoxin-like fold. It is predominantly found in plant cytokinin dehydrogenase 1, where it is capable of binding both FAD and cytokinin substrates. The substrate displays a 'plug-into-socket' binding mode that seals the catalytic site and precisely positions the carbon atom undergoing oxidation in close contact with the reactive locus of the flavin [PMID: 15321719].
