comment
  • FUNCTION Catalyzes the oxidation of cytokinins, a family of N(6)-substituted adenine derivatives, where the substituent is an isopentenyl group (Probable). Cytokinins are plant hormones essential for plant growth, development, and stress responses (Probable). Exhibits specific activities toward trans-zeatin (tZ) and isopentenyladenine (iP) (PubMed:36031806). Plays a role in lamina joint inclination (PubMed:36031806). Regulates cell proliferation and vascular bundle number on the abaxial side of lamina joint (PubMed:36031806).CATALYTIC ACTIVITY N(6)-dimethylallyladenine + A + H2O = 3-methyl-2-butenal + adenine + AH2COFACTOR Monomer.SUBCELLULAR LOCATION Expressed in inflorescence meristems (PubMed:15976269). Highly expressed in lamina joints, and mainly in the parenchyma cells and vascular bundles on the abaxial side of the lamina joint (PubMed:36031806). Expressed in roots, stems, leaves and young panicles (PubMed:36031806).INDUCTION Induced by isopentenyladenine, trans-zeatin and 24-epibrassinolide.DISRUPTION PHENOTYPE Increased leaf erectness, asymmetric growth and development of lamina joint.MISCELLANEOUS Plants over-expressing CKX3 exhibit decreased leaf erectness.SIMILARITY Belongs to the oxygen-dependent FAD-linked oxidoreductase family.
