ster·oid mon·o·ox·y·ge·na·ses

enzymes catalyzing addition of hydroxyl groups to the steroid rings using O2; differentiated into, for example, steroid 11β-monooxygenase, steroid 17α-monooxygenase, and steroid 21-monooxygenase, in accordance with the position of the catalytically introduced hydroxyl group.
