In enzymology, a NAD+ synthase (glutamine-hydrolysing) () is an enzyme that catalyzes the chemical reaction :ATP + deamido-NAD+ + L-glutamine + H2O AMP + diphosphate + NAD+ + L-glutamate. In eukaryotes, this enzyme contains a glutaminase domain related to nitrilase. The substrates of this enzyme are ATP, deamido-NAD+, L-glutamine, and H2O, whereas its 4 products are AMP, diphosphate, NAD+, and glutamate This enzyme belongs to the family of ligases, specifically those forming carbon-nitrogen bonds carbon-nitrogen ligases with glutamine as amido-N-donor. The systematic name of this enzyme class is deamido-NAD+:L-glutamine amido-ligase (AMP-forming). Other names in common use include NAD+ synthetase (glutamine-hydrolysing), nicotinamide adenine dinucleotide synthetase (glutamine), desamidonicotinamide adenine dinucleotide amidotransferase, and DPN synthetase. This enzyme participates in glutamate metabolism and nicotinate and nicotinamide metabolism. ==Structural studies== As of late 2007, 7 structures have been solved for this class of enzymes, with PDB accession codes , , , , , , and . 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「NAD+ synthase (glutamine-hydrolysing)」の詳細全文を読む スポンサード リンク
