Denitrification, membrane-bound enzymes

Two types of dissimilatory nitrate reductases, localized in either the cytoplasmic membrane or the periplasm, are widespread among bacteriaT" The cytoplasmic membrane-bound nitrate reductase (Nar) catalyzes the first steps of denitrification (NOs N02 NO N2O N2) and nitrate ammonification (NOs"N02 NH3). These reactions are the terminal electron-transfer reactions during anaerobic respiration, the enzymes being part of a redox loop generating a proton-motive force capable of driving ATP synthesis.Periplasmic nitrate reductase (Nap) participates in cellular redox processes, aerobic denitrification, and nitrate scavenging. ... [Pg.2783]
