steroid hydroxylase activity oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen, reduced iron-sulfur protein as one donor, and incorporation of one atom of oxygen ecdysteroid 2-hydroxylase activity https://github.com/geneontology/go-ontology/issues/29033 MetaCyc:RXN-14682 MetaCyc:RXN-24932 Catalysis of the hydroxylation of an ecdysteroid at carbon position 2. GO:0042768 Note that in the ecdysteroidogenic pathway, this activity catalyzes the conversion of 2-deoxyecdysone to ecdysone. It can also catalyze the conversion of 2,22-dideoxyecdysone (ketotriol) to 22-deoxyecdysone. RHEA:83255 RHEA:82351 molecular_function MetaCyc:RXN-14679
