Yeast Alcohol Dehydrogenase I, Saccharomyces cerevisiae fermentative enzyme

Overview

The cytoplasmic yeast alcohol dehydrogenase I crystallized at 5 degrees C, as hexagonal plates or short columns in the presence of NAD+ and, 2,2,2-trifluoroethanol, in sodium, N-tris(hydroxymethyl)methyl-3-aminopropanesulfonate buffer at pH 8.2 to, 8.6, using polyethylene glycol 4000 as precipitant. X-ray diffraction data, to 3.2 A resolution show that the crystals are hexagonal in space group, P622 with unit cell dimensions a = b = 147.9 A, c = 69.1 A. There is one, subunit of the tetrameric enzyme per asymmetric unit, giving a packing, density of 2.9 A3/Da.
