Protein
Cytochrome P450 734A4
Organism
Oryza sativa subsp. japonica
Function
Cytochrome P450 involved in brassinosteroids (BRs) inactivation and regulation of BRs homeostasis. Is a multifunctional and multisubstrate enzyme that controls the endogenous bioactive BR content both by direct inactivation of castasterone and by decreasing the levels of BR precursors. Catalyzes the oxidation of carbon 22 hydroxylated BR intermediates to produce C26 oxidized metabolites.
Similarity
Belongs to the cytochrome P450 family.
