Catalyzes the hydroxylation at C-21 of progesterone and 17alpha-hydroxyprogesterone to respectively form 11-deoxycorticosterone and 11-deoxycortisol, intermediate metabolites in the biosynthetic pathway of mineralocorticoids and glucocorticoids. Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (CPR; NADPH-ferrihemoprotein reductase)"],"length":494,"sequence":"MLLLGLLLLPLLAGARLLWNWWKLRSLHLPPLAPGFLHLLQPDLPIYLLGLTQKFGPIYRLHLGLQDVVVLNSKRTIEEAMVKKWADFAGRPEPLTYKLVSRNYPDLSLGDYSLLWKAHKKLTRSALLLGIRDSMEPVVEQLTQEFCERMRAQPGTPVAIEEEFSLLTCSIICYLTFGDKIKDDNLMPAYYKCIQEVLKTWSHWSIQIVDVIPFLRFFPNPGLRRLKQAIEKGDHIVEMQLRQHKESLVAGQWRDMMDYMLQGVAQPSMEEGSGQLLEGHVHMAAVDLLIGGTETTANTLSWAVVFLLHHPEIQQRLQEELDHELGPGASSSRVPYKDRARLPLLNATIAEVLRLRPVVPLALPHRTTRPSSISGYDIPEGTVIIPNLQGAHLDETVWERPHEFWPDRFLEPGKNSRALAFGCGARVCLGEPLARLELFVVLTRLLQAFTLLPSGDALPSLQPLPHCSVILKMQPFQVRLQPRGMGAHSPGQSQ","proteome":null,"gene":"CYP21A2","go_terms":[{"identifier":"GO:0004497","name":"monooxygenase activity","category":{"code":"F","name":"molecular_function"}},{"identifier":"GO:0005506","name":"iron ion binding","category":{"code":"F","name":"molecular_function"}},{"identifier":"GO:0016705","name":"oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen","category":{"code":"F","name":"molecular_function"}},{"identifier":"GO:0020037","name":"heme binding","category":{"code":"F","name":"molecular_function"}}],"protein_evidence":2,"source_database":"unreviewed","is_fragment":false,"in_alphafold":true,"in_bfvd":false,"ida_accession":"a02e61ba6c64bb9a9c779746e03a6c43264a16fb","counters":{"domain_architectures":520850,"entries":12,"isoforms":0,"proteomes":0,"sets":1,"structures":0,"taxa":1,"dbEntries":{"cathgene3d":1,"ssf":1,"pfam":1,"cdd":1,"panther":1,"prosite":1,"prints":2,"interpro":4},"proteome":0,"taxonomy":1,"similar_proteins":520850}}}
