Abstract
Phosphorylating glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a key enzyme in glycolysis. Single crystals of NAD-dependent GAPDH from Escherichia coli have been obtained by vapour diffusion at room temper ature using trisodium citrate as precipitant. In almost the same cryst allization conditions, two kinds of crystals were found to be suitable for X-ray diffraction. The crystals with only one half of a tetramer in the asymmetric unit were chosen for high-resolution analysis. They belonged to space group C222(1), with cell dimensions a = 79.1, b = 18 9.6 and c = 122.2 Angstrom. These crystals diffracted to 1.8 Angstrom resolution.
