May be involved in carotenoid cleavage. Binds 1 Fe(2+) ion per subunit. Interacts with VAR3 (PubMed:15340011). Interacts with PGM48 (PubMed:27895226). Mostly expressed in flowers (e.g. sepals and petals), siliques, seeds, leaves and cotyledons. Probably proteolytically degraded by PGM48 during leaves senescence (PubMed:28534654). Not induced by drought stress. Belongs to the carotenoid oxygenase family.
