Phosphoribosyl-ATP pyrophosphatase

This enzyme [EC 1.1.1.23] catalyzes the reaction of l-histidinol with two NAD+ to produce L-histidine and two NADH. L-Histidinal will also serve as a substrate for this protein. The Neurospora crassa enzyme will also catalyze the reactions of phosphoribosyl-AMP cyclohydrolase [EC 3.5.4.19] and phosphoribosyl-ATP pyrophosphatase [EC 3.6.1.31]. [Pg.342]

This enzyme [EC 3.5.4.19] catalyzes the hydrolysis of 5-phosphoribosyl-AMP to produce 5-(5-phospho-D-ribo-sylaminoformimino)-l-(5-phosphoribosyl)tmidazole-4-carboxamide. The enzyme isolated from Neurospora crassa can also catalyze the reactions of histidinol dehydrogenase and phosphoribosyl-ATP pyrophosphatase. [Pg.556]
