Aconitase inactivation alters the redox and energy status of S. epidermidis. (A) At the indicated times during the growth cycle, intracellular concentrations of NAD and NADH were determined in S. epidermidis strain 1457. (B) Similarly, the concentrations of reduced and oxidized NAD were determined for strain 1457-acnA. (C) ATP concentrations were determined for strains 1457 and 1457-acnA. The results are presented as the means plus standard errors of the means (error bars) of duplicate determinations for at least two independent experiments.
