GenProp0200 periplasmic nitrate reductase~Denitrifying bacteria reduce nitrate via three distinct nitrate reductase systems. Two of these are assciated with energy-conserving electron transport systems, distinguished by cellular location and generation of a proton motive force, and the other with nitrate assimilation. All three types involve binding of molybdopterin to the active site of nitrate reductase where reduction occurs. Unlike membrane-associated nitrate reductases, periplasmic nitrate reductase cannot itself act as a coupling site for proton translocation, but can participate indirectly in respiration by virtue of the consumption of electrons derived from NADH via the proton translocating NADH dehydrogenase. Expressed aerobically as well as anearobically in gram-negative bacteria, periplasmic nitrate reductase is a two-subunit enzyme comprised of a catalytic subunit binding molybdopterin and containing a twin-arginine signal motif, and a cytochrome subunit, whose redox partner is a membrane-bound electron transfer protein. Other essential components for this denitrifying system include a proposed chaperone, and at least five other components identified in different combinations in different bacteria [1]. Lacking the membrane-bound c-type cytochrome component, in Wolinella succinogenes electron transport to nitrate reductase from one or more of these other gene products has been demonstrated [2].
