1.9.6.1 physiological function napAB expression is required for anaerobic growth recovery by DELTAnarXL (a deletion encompassing the bulk of narXL) 711653 1.9.6.1 physiological function Salmonella enterica serovar Typhimurium uses the periplasmic nitrate reductase to support its growth on the low nitrate concentrations encountered in the gut, a strategy that may be shared with other enteric pathogens -, 742645 1.9.6.1 physiological function the anaerobic reduction of NO3- to N2O is lower in Bradyrhizobium japonicum than in Bradyrhizobium diazoefficiens due to impaired periplasmic nitrate reductase (Nap) activity in B. japonicum. Impaired Nap activity in B. japonicum is due to low Nap protein levels -, 765355 1.9.6.1 physiological function the Nap enzyme from Cupriavidus necator catalyzes nitrate reduction to consume the excess of reducing equivalents generated by consumption of the carbon source -, 742319 1.9.6.1 physiological function the Nap enzyme from Rhodobacter sphaeroides catalyzes nitrate reduction to consume the excess of reducing equivalents generated by consumption of the carbon source 742319 1.9.6.1 physiological function the Nap enzyme from Shewanella gelidimarina catalyzes nitrate reduction to consume the excess of reducing equivalents generated by consumption of the carbon source 742319 1.9.6.1 physiological function the Nap-deficient mutant KD102 shows increased diauxic lag when switched from aerobic to anoxic respiration, suggesting Nap is responsible for shorter lags and helps in adaptation to anoxic metabolism after transition from aerobic conditions 696917 1.9.6.1 physiological function the single subunit nitrate reductase (Nap) appears to be involved in both the assimilatory and the dissimilatory denitrification pathways. The role in the former is supported by the methanol growth deficiency of the mutant when nitrate is used as a nitrogen source, and the role in the latter is supported by the lack of accumulation of N2O in the mutant -, 741478
