Subcellular location

Subcellular Location:
Mitochondrion matrix

Function

Function:
NAD-dependent 17-beta-hydroxysteroid dehydrogenase with highest activity towards estradiol. Has very low activity towards testosterone. The heteroteramer with CBR4 has NADH-dependent 3-ketoacyl-acyl carrier protein reductase activity. May play a role in biosynthesis of fatty acids in mitochondria.
Pathway:
Steroid biosynthesis; estrogen biosynthesis.; Lipid metabolism; fatty acid biosynthesis.
Catalytic Activity:
17-beta-estradiol + NAD(P)(+) = estrone + NAD(P)H.; Testosterone + NAD(+) = androstenedione + NADH.
Active Site:
ACT_SITE 169 169 Proton acceptor.
