摘要
The ubiquitous NAD(+) synthetase catalyzes the key step in the biosynthesis of nicotinamide adenine dinucleotide. NH3-dependent NAD(+) synthetase from Helicobacter pylori was purified to homogeneity and crystallized using PEG 1500 as a preciptant. The crystal diffracted up to a resolution of 2.3+ and was found to belong to space group C2 with unit cell dimensions of a = 93.8, b = 48.3, c = 64.2 A and alpha = gamma = 90, beta = 110.0degrees.
