Hydroxylase

Definition

Hydroxylasen sind Enzyme aus der Gruppe der Oxidoreduktasen (EC1). Sie katalysieren eine Hydroxylierung, d.h. die Integration einer Hydroxygruppe (-OH) in ein Molekül.

Phenolhydroxylase	Phenol → Brenzcatechin
Phytanoyl-CoA-Hydroxylase	Phytanoyl-CoA → 2-Hydroxyphytanoyl-CoA
Steroid-21-Hydroxylase	Pregnenolon → 21-Hydroxypregnenolon
Steroid-11β-Hydroxylase	11-Deoxycortisol → Cortisol
Steroid-17α-Hydroxylase (CYP17A1)	Pregnenolon → 17α-Hydroxypregnenolon
