An enzyme is present in extracts of guinea pig polymorphonuclear leukocytes which can catalyze the hydrolysis of pyridine nucleotides. The enzyme is equally active toward nicotinamide adenine dinucleotide (NAD) or NAD phosphate, has an acid pH optimum, and is inhibited by either nicotinamide or isonicotinic acid hydrazide. This enzyme might be involved in the regulation of the pyridine nucleotide concentration within the leukocyte.
豚鼠多形核白细胞提取物中存在一种能催化吡啶核苷酸水解的酶。该酶对烟酰胺腺嘌呤二核苷酸(NAD)或烟酰胺腺嘌呤二核苷酸磷酸(NADP)的活性相同,最适pH值呈酸性,且受烟酰胺或异烟肼抑制。这种酶可能参与白细胞内吡啶核苷酸浓度的调节。
