== Publication Abstract from PubMed ==

Mouse 3(17)alpha-hydroxysteroid dehydrogenase (AKR1C21) is a bifunctional enzyme that catalyses the oxidoreduction of the 3- and 17-hydroxy/keto groups of steroid substrates such as oestrogens, androgens and neurosteroids. The structure of the AKR1C21-NADPH binary complex was determined from an orthorhombic crystal belonging to space group P2(1)2(1)2(1) at a resolution of 1.8 A. In order to identify the factors responsible for the bifunctionality of AKR1C21, three steroid substrates including a 17-keto steroid, a 3-keto steroid and a 3alpha-hydroxysteroid were docked into the substrate-binding cavity. Models of the enzyme-coenzyme-substrate complexes suggest that Lys31, Gly225 and Gly226 are important for ligand recognition and orientation in the active site.

[[http://www.uniprot.org/uniprot/AK1CL_MOUSE AK1CL_MOUSE]] NADP-dependent 17-alpha-hydroxysteroid dehydrogenase that converts 5-alpha-androstane-3,17-dione into androsterone. Has lower 3-alpha-hydroxysteroid dehydrogenase activity. Has broad substrate specificity and acts on various 17-alpha-hydroxysteroids, 17-ketosteroids, 3-alpha hydroxysteroids and 3-ketosteroids. Reduction of keto groups is strictly stereoselective. Reduction of 17-ketosteroids yields only 17-alpha-hydroxysteroids. Likewise, reduction of 3-ketosteroids yields only 3-alpha-hydroxysteroids.<ref>PMID:15577209</ref> <ref>PMID:16018803</ref> <ref>PMID:17034817</ref>
