Glyceraldehyde-3-phosphate dehydrogenase from spinach chloroplasts has been crystallized by vapour diffusion in the pH range 7-8.5 in (NH4)(2)SO4 and Tris-HCl buffer or potassium phosphate buffer at room temperature. Crystals of the A(4) isoform, grown at pH 8.5 in Tris-HCl buffer, diffract to 3.0 Angstrom (at 100 K) using synchrotron radiation. The crystals belong to the orthorhombic C222 space group, with unit-cell dimensions a = 145.9, b = 185.9 and c = 106.3 Angstrom, and probably contain one tetramer per asymmetric unit. Structure determination by molecular replacement is in progress.

Abstract
Glyceraldehyde-3-phosphate dehydrogenase from spinach chloroplasts has been crystallized by vapour diffusion in the pH range 7-8.5 in (NH4)(2)SO4 and Tris-HCl buffer or potassium phosphate buffer at room temperature. Crystals of the A(4) isoform, grown at pH 8.5 in Tris-HCl buffer, diffract to 3.0 Angstrom (at 100 K) using synchrotron radiation. The crystals belong to the orthorhombic C222 space group, with unit-cell dimensions a = 145.9, b = 185.9 and c = 106.3 Angstrom, and probably contain one tetramer per asymmetric unit. Structure determination by molecular replacement is in progress.File in questo prodotto:
