Protein
Steroid 21-hydroxylase
Gene
CYP21
Organism
Canis lupus (Gray wolf)
Status
Reviewed - Annotation score: 4 out of 5 - Protein inferred from homologyi

Functioni

Specifically catalyzes the 21-hydroxylation of steroids. Required for the adrenal synthesis of mineralocorticoids and glucocorticoids.

Catalytic activityi

A C(21) steroid + (reduced NADPH--hemoprotein reductase) + O2 = a 21-hydroxy-C(21)-steroid + (oxidized NADPH--hemoprotein reductase) + H2O.

Cofactori

Heme group By similarity.
