Crystallization and preliminary X-ray diffraction study of aldehyde reductase from a red yeast, Sporobolomyces salmonicolor

Crystals of aldehyde reductase from a red yeast, Sporobolomyces salmonicolor, have been grown from an ammonium sulfate solution, pH 7.0, by means of the vapor-diffusion procedure. The crystals belong to the hexagonal system, space group P6₁22 or its enantiomorph, P6₅22, with unit-cell dimensions of a = 72.2 and c = 320 Å. The X-ray diffraction patterns extend to at least 2 Å resolution with the use of synchrotron radiation. The crystals are stable on exposure to X-rays and suitable for high-resolution X-ray structure determination.
