evolution
-
3,17beta-hydroxysteroid dehydrogenase is a member of the short-chain dehydrogenase/reductase (SDR) superfamily
evolution
-
enzyme Tsol-17betaHSD belongs to the short-chain dehydrogenase/reductase (SDR) protein superfamily, it shares motifs and activity with the type 3 enzyme of some other species
evolution
enzyme AKR1C35 is a member of the aldo–keto reductase (AKR) 1C subfamily in the AKR superfamily
evolution
-
3,17beta-hydroxysteroid dehydrogenase is a member of the short-chain dehydrogenase/reductase (SDR) superfamily
-
malfunction
-
compared to the wild-type Comamonas testosteroni, degradation ability of testosterone and cholesterol is almost lost, and degradation of estradiol is decreased in the 3,17beta-HSD knockout mutant. Degradation of testosterone and cholesterol is obviously increased in the 3,17beta-HSD overexpression mutant. The growths in the medium with testosterone, cholesterol or estradiol are impaired in 3,17beta-HSD knockout mutant
malfunction
-
AKR1C3 siRNA reduces androgen receptor signaling in VCaP cells. Small-molecule inhibitors inhibit both the enzymatic and coactivator functions of AKR1C3 resulting in androgen-dependent prostate cancer and CRPC regression
malfunction
mutation of Val54Ala, but not Cys310Phe, significantly impairs the 3beta-hydroxysteroid dehydrogenase enzyme activity, suggesting that Val54 plays a critical role in recognition of the steroidal substrate

-
metabolism
-
Comamonas testosteroni strain ATCC11996 is a gram-negative bacterium which can use steroids as carbon and energy source. 3,17beta-HSD is an enzyme which is involved in the complete oxidative degradation of the steroid skeleton, induced in the presence of these compounds in the culture medium
metabolism
-
the enzyme catalyzes the last step in the biosynthesis of the potent androgen testosterone (T), by stereoselectively reducing the C17 ketone of 4-androstene-3,17-dione (4-dione), with NADPH as cofactor

-
physiological function
-
3,17beta-hydroxysteroid dehydrogenase is a key enzyme in steroid degradation
physiological function
-
castration-resistant prostate cancer may occur by several mechanisms including the upregulation of androgen receptor, coactivators, and steroidogenic enzymes, including aldo keto reductase 1C3 (AKR1C3). AKR1C3 converts weaker 17-keto androgenic precursors to more potent 17-hydroxy androgens and is consistently the major upregulated gene in castration-resistant prostate cancer, CRPC. AKR1C3 enhances androgen signaling and prostate cancer xenograft growth. AKR1C3 is a receptor- and tissue-selective pharmacologically targetable coactivator that promotes prostate cancer growth, AKR1C3-dependent R1881-induced androgen receptor transactivation in HEK-293 cells
physiological function
-
17beta-hydroxysteroid dehydrogenases (17beta-HSD) are key enzymes involved in the formation (reduction) and inactivation (oxidation) of sex steroids. Taenia solium cysticerci are able to synthesize sex steroid hormones in vitro when precursors are provided in the culture medium
physiological function
enzyme AKR1C35 oxidizes various xenobiotic alicyclic alcohols using NAD+
physiological function
-
17beta-hydroxysteroid dehydrogenase type 3 catalyzes the last step in the biosynthesis of the potent androgen testosterone by stereoselectively reducing the C17 ketone of 4-androstene-3,17-dione (4-dione), with NADPH as cofactor
physiological function
-
conversion of testosterone to 4-dione detected in abdominal adipose tissue is caused by 17beta-HSD type 2 which is localized in the vasculature of the adipose compartment
physiological function
-
3,17beta-hydroxysteroid dehydrogenase is a key enzyme in steroid degradation
-
additional information
-
PhaR is a repressor that controls 3,17beta-HSD expression, phaR knock-out mutants grow at higher rates and produce more protein in the presence of steroids as carbon source. PhaR also regulates other genes that relate to steroid degradation. Estradiol and cholesterol both cannot induce betahsd gene expression in both wild-type and mutant Comamonas testosteroni

activities of the two key enzymes for testosterone biosynthesis, 3-beta-HSD and 17-beta-HSD, are significantly affected by rats subjected to semi-synthetic diet. Both enzyme activities are significantly decreased in interstitial cell homogenates from rats fed with a soybean diet and a grape seed diet compared with the levels observed in the group fed a olive or coconut diet
