[NADPase and NADase in the peritoneal macrophages of mice].

Murine peritoneal macrophages are able to hydrolyse NAD+ and NADP+. The NADPase activity exceeds that of NADase by 22-24%. The pH optima for both the enzymes are, respectively, 6.0 and 7.0. NAD hydrolysis is considerably activated by Mg2+, whereas NADP hydrolysis remains not affected. NAD+ does not change NADPase activity, while NADase activity is inhibited by NADP by 25-30%. A diazonium salt of sulfanilic acid, known to be an inhibitor of cell plasma membranes, does not affect NADP+ hydrolysis and causes a 20-30% retardation of NAD+ hydrolysis. The data obtained suggest that murine peritoneal macrophages contain two hydrolytic enzymes: NADase and NADPase.
