Abstract excerpt
NADH dehydrogenase-2 (NDH-2) from Escherichia coli respiratory chain is a membrane-bound cupric-reductase encoded by ndh gene. Here, we report that the respiratory system of a ndh deficient strain suffered a faster inactivation than that of the parental strain in the presence of tert-butyl hydroperoxide due to endogenous copper. The inactivation was similar for both strains when copper concentration increased in...
