CC -!- FUNCTION: Cytochrome P450 involved in brassinosteroids (BRs)
CC inactivation and regulation of BRs homeostasis. Inactivates the BRs
CC castasterone (CS) and brassinolide (BL) through carbon 26
CC hydroxylation. Acts in association with CYP72C1 to inactivate BRs and
CC modulate photomorphogenesis. {ECO:0000269|PubMed:10611382,
CC ECO:0000269|PubMed:14605216, ECO:0000269|PubMed:15773851,
CC ECO:0000269|PubMed:20396969, ECO:0000269|PubMed:20669042}.
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 -!- INDUCTION: By brassinolide (BL), auxin and dark treatment.
CC {ECO:0000269|PubMed:14605216, ECO:0000269|PubMed:20396969}.
CC -!- DISRUPTION PHENOTYPE: No visible phenotype under normal growth
CC condition, but reduced responsiveness of hypocotyls to light and
CC increased responsiveness to brassinolide (BL). Strong reduction of C-26
CC hydroxylase activity. {ECO:0000269|PubMed:14605216,
CC ECO:0000269|PubMed:15773851}.
CC -!- MISCELLANEOUS: Plants overexpressing CYP734A1 exhibit severe dwarfism.
CC -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
