A Salt-Inhibited Cytochrome c Reductase Obtained from the Moderately Halophilic Bacterium, Micrococcus halodenitrificans

RESUMO
A membrane-bound cytochrome c reductase from Micrococcus halodenitrificans was inhibited by NaCl at concentrations as low as 0.05 m. The inhibition was competitive with respect to cytochrome c and noncompetitive with respect to reduced nicotinamide adenine dinucleotide. Thus the effect of NaCl was to increase the apparent Km of the enzyme for cytochrome c and not to inhibit the intrinsic activity of the enzyme.
