Protein

3-oxo-5-alpha-steroid 4-dehydrogenase 2

Gene

SRD5A2

Organism
Macaca fascicularis (Crab-eating macaque) (Cynomolgus monkey)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

Converts testosterone (T) into 5-alpha-dihydrotestosterone (DHT) and progesterone or corticosterone into their corresponding 5-alpha-3-oxosteroids. It plays a central role in sexual differentiation and androgen physiology.

Catalytic activityi

A 3-oxo-5-alpha-steroid + NADP+ = a 3-oxo-Delta(4)-steroid + NADPH.

pH dependencei

Optimally active at acidic pHs.
