– Catalyzes the dehydrogenation of 17-beta-hydroxysteroids. May also exhibit significant activity with a variety of cyclic and alicyclic alcohols. Uses both NAD and NADP, but the activity is much greater with NAD than with NADP. AKR1C3 Protein, Mouse, Recombinant (His & Myc) is expressed in E. coli expression system with N-10xHis and C-Myc tag. The predicted molecular weight is 44.5 kDa and the accession number is Q8VC28.
