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 Å and α = γ = 90, β = 110.0°.

Keywords: amidotransferase, helicobacter pylori, synthetase
