Protein

17-beta-hydroxysteroid dehydrogenase type 6

Gene
HSD17B6, RODH
Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

NAD-dependent oxidoreductase with broad substrate specificity that shows both oxidative and reductive activity (in vitro). Has 17-beta-hydroxysteroid dehydrogenase activity towards various steroids (in vitro). Converts 5-alpha-androstan-3-alpha,17-beta-diol to androsterone and estradiol to estrone (in vitro). Has 3-alpha-hydroxysteroid dehydrogenase activity towards androsterone (in vitro). Has retinol dehydrogenase activity towards all-trans-retinol (in vitro). Can convert androsterone to epi-androsterone. Androsterone is first oxidized to 5-alpha-androstane-3,17-dione and then reduced to epi-andosterone. Can act on both C-19 and C-21 3-alpha-hydroxysteroids.3 Publications

Catalytic activityi

17-beta-estradiol + NAD(P)+ = estrone + NAD(P)H.
Testosterone + NAD+ = androstenedione + NADH.
All-trans-retinol-[cellular-retinol-binding-protein] + NAD+ = all-trans-retinal-[cellular-retinol-binding-protein] + NADH.

Kineticsi

The kinetic parameters were determined using microsomes from transfected cells.
