17β-Hydroxysteroid dehydrogenase 1 (17β-HSD1) is an enzyme that in humans is encoded by the HSD17B1 gene.^[5]^[6]^[7] This enzyme oxidizes or reduces the C17 hydroxy/keto group of androgens and estrogens and hence is able to regulate the potency of these sex steroids

Function[edit]

This enzyme is responsible for the interconversion of estrone (E1) and estradiol (E2) and for the interconversion of androstenedione and testosterone:

17β-estradiol + NADP⁺ +

\rightleftharpoons

estrone + NADPH + H⁺

testosterone + NADP⁺ +

\rightleftharpoons

androstenedione + NADPH + H⁺

The human 17β-HSD1 isozyme is highly specific for estrogens over androgens whereas the rodent isozyme is less specific.^[8]

Discovery[edit]

Human 17β-HSD1 was the first enzyme of the 17β-HSD family to be cloned and to have its sequence identified.^[9]^[10] Its three-dimensional structure is also the first example of any human steroid-converting enzyme.^[11]

Structure[edit]

This enzyme contains a short-chain dehydrogenase domain that contains a characteristic 3-layer (αβα) sandwich known as a Rossmann fold. The human enzyme contains 327 amino acids and exists as a homodimer with two identical subunits of 34.5 kDa ^[10]^[12] The N-terminal short-chain dehydrogenase domain contains binding site for the NADP⁺/NADPH cofactor. A narrow, hydrophobic C-terminal domain contains a binding pocket for the steroid substrate.

Clinical significance[edit]

Estradiol stimulates while dihydrotestosterone (DHT) inhibits breast cancer growth. Furthermore 17β-HSD1 levels positively correlate with estradiol and negatively correlate with DHT levels in breast cancer cells. Hence 17β-HSD1 represents a possible drug target for breast cancer treatment.^[13]
