Function
CPRC1_CANPA NADPH-dependent conjugated polyketone reductase with broad substrate specificity and strict stereospecificity. Reduces ketopantoyl lactone (2-dehydropantolactone) and isatin. Does not act on menadione, p-nitrobenzaldehyde and pyridine-3-aldehyde.[1] [2]
Publication Abstract from PubMed
Conjugated polyketone reductase (CPR-C1) from Candida parapsilosis IFO 0708 is a member of the aldo-keto reductase (AKR) superfamily and reduces ketopantoyl lactone to D-pantoyl lactone in a NADPH-dependent and stereospecific manner. We determined the crystal structure of CPR-C1.NADPH complex at 2.20 A resolution. CPR-C1 adopted a triose-phosphate isomerase (TIM) barrel fold at the core of the structure in which Thr25 and Lys26 of the GXGTX motif bind uniquely to the adenosine 2'-phosphate group of NADPH. This finding provides a novel structural basis for NADPH binding of the AKR superfamily. (c) Proteins 2013;. (c) 2013 Wiley Periodicals, Inc.
