In enzymology, a cholestenone 5alpha-reductase (EC 1.3.1.22) is an enzyme that catalyzes the chemical reaction
- 5alpha-cholestan-3-one + NADP+ cholest-4-en-3-one + NADPH + H+
Thus, the two substrates of this enzyme are 5alpha-cholestan-3-one and NADP+, whereas its 3 products are cholest-4-en-3-one, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 3-oxo-5alpha-steroid:NADP+ Delta4-oxidoreductase. Other names in common use include testosterone Delta4-5alpha-reductase, steroid 5alpha-reductase, 3-oxosteroid Delta4-dehydrogenase, 5alpha-reductase, steroid 5alpha-hydrogenase, 3-oxosteroid 5alpha-reductase, testosterone Delta4-hydrogenase, 4-ene-3-oxosteroid 5alpha-reductase, reduced nicotinamide adenine dinucleotide, phosphate:Delta4-3-ketosteroid 5alpha-oxidoreductase, 4-ene-5alpha-reductase, Delta4-3-ketosteroid 5alpha-oxidoreductase, cholest-4-en-3-one 5alpha-reductase, and testosterone 5alpha-reductase.

- BACKGROUND: Altered DNA methylation in CpG islands of gene promoters has been implicated in prostate cancer (PCa) progression and can be used to predict disease outcome. In this study, we determine whether methylation changes of androgen biosynthesis pathway (ABP)-related genes in patients' plasma c

- PURPOSE: In men with symptomatic benign prostatic hyperplasia 5α-reductase inhibitors are a main modality of treatment. More than 30% of men do not respond to the therapeutic effects of 5α-reductase inhibitors. We have found that a third of adult prostate samples do not express 5α-reductase type

- AIM: De novo androgen synthesis is thought to be involved in the progression to castration-resistant prostate cancer (CRPC) during androgen-deprivation therapy (ADT). During androgen synthesis, 5α-reductase encoded by SRD5A catalyses testosterone into more active dihydrotestosterone and may be invo
