isocitrate dehydrogenase (NADP+)

isocitrate dehydrogenase (NADP+)
iso·ci·trate de·hy·dro·gen·ase (NADP+) (i″so-sĭґtrāt de-hiґdrə-jən-ās) [EC 1.1.1.42] an enzyme of the oxidoreductase class that catalyzes the oxidative decarboxylation of isocitrate to form α-ketoglutarate, using NADP+ as an electron acceptor. The enzyme exists as two isozymes, one cytoplasmic and one mitochondrial, requires Mg2+ or Mn2+, and occurs in all tissues. The reaction serves to maintain the level of reducing equivalents within the cell.
