Crystallization and preliminary X-ray crystallographic analysis of a carbonyl reductase from Candida parapsilosis.


ABSTRACT: A novel short-chain NADPH-dependent (S)-1-phenyl-1,2-ethanediol dehydrogenase (SCR) has been crystallized. Two distinct but related crystal forms of SCR were obtained using the hanging-drop vapour-diffusion method and a reservoir solution consisting of 18%(w/v) polyethylene glycol 2000 monomethyl ether and 8%(v/v) 2-propanol as the precipitant. The crystals were rhomboid in shape with average dimensions of 0.3 x 0.3 x 0.4 mm and diffracted to a resolution of 2.7-3.0 A. The crystal forms both belong to space group P2(1)2(1)2(1) and have unit-cell parameters a = 104.7, b = 142.8, c = 151.8 A and a = 101.1, b = 146.0, c = 159.8 A. The calculated values of V(M), rotation-function and translation-function solutions and consideration of potential crystal packing suggest that there are eight protein subunits per asymmetric unit.
