NADP 167-171 aldo-keto reductase family 1 member C4 Homo sapiens 156-166 19013211-1 2009 Two members of the human aldo-keto reductase (AKR) superfamily participate in the biosynthesis of bile acids by catalyzing the NADP(H) dependent reduction of 3-keto groups (AKR1C4) and Delta4 double bonds (AKR1D1) of oxysterol precursors. NADP 127-134 aldo-keto reductase family 1 member C4 Homo sapiens 173-179 11037109-10 2000 Except for AKR1C4, the enzymes had a strong preference for NADPH over NADH, and the highest activities were measured with an NADPH-regenerating system. NADP 59-64 aldo-keto reductase family 1 member C4 Homo sapiens 11-17 11037109-10 2000 Except for AKR1C4, the enzymes had a strong preference for NADPH over NADH, and the highest activities were measured with an NADPH-regenerating system. NADP 125-130 aldo-keto reductase family 1 member C4 Homo sapiens 11-17 9261071-4 1997 The determination of the structure of 3 alpha-HSD in complex with NADP+ and testosterone (a competitive inhibitor) will help to further our understanding of steroid recognition and hormone regulation by mammalian HSDs.
