HSD17B3 (human), recombinant protein

Protein function: Favors the reduction of androstenedione to testosterone. Uses NADPH while the two other EDH17B enzymes use NADH (PubMed:26545797, PubMed:8075637, PubMed:16216911). Androgens such as epiandrosterone, dehydroepiandrosterone, androsterone and androstanedione are accepted as substrates and reduced at C-17. Can reduce 11-ketoandrostenedione as well as 11beta-hydroxyandrostenedione at C-17 to the respective testosterone forms (PubMed:16216911). [The UniProt Consortium]
