CC -!- FUNCTION: Cytochrome P450 involved in brassinosteroids (BRs)
CC inactivation and regulation of BRs homeostasis. Is a multifunctional
CC and multisubstrate enzyme that controls the endogenous bioactive BR
CC content both by direct inactivation of castasterone (CS) and by
CC decreasing the levels of BR precursors. Catalyzes the oxidation of
CC carbon 22 hydroxylated BR intermediates to produce C26 oxidized
CC metabolites. {ECO:0000269|PubMed:21418356}.
CC -!- COFACTOR:
CC Name=heme; Xref=ChEBI:CHEBI:30413; Evidence={ECO:0000250};
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000255}; Single-pass membrane
CC protein {ECO:0000255}.
CC -!- TISSUE SPECIFICITY: Expressed in roots, shoot apex, leaf sheaths and
CC leaf blades. {ECO:0000269|PubMed:21418356}.
CC -!- INDUCTION: By brassinolide (BL) and dark treatment.
CC {ECO:0000269|PubMed:21418356}.
CC -!- MISCELLANEOUS: Plants overexpressing CYP734A2 show a dwarf phenotype,
CC characterized by abnormal leaves with stiff, tortuous blades,
CC undeveloped leaf sheaths, no flowering and bear seeds. Over-expression
CC of CYP734A2 causes an important reduction of the levels of the BRs
CC castasterone (CS), 6-deoxocastasterone (6-deoxoCS) and 6-
CC deoxotyphasterol (6-deoxoTY).
CC -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
