NADH-dependent reductase activities of OmcA and MtrC. Temperature (A) and pH (B) dependence of Fe(III) reductase activities [micromoles of Fe(III)-NTA reduced per minute per milligram of protein] of OmcA (○) and MtrC (•) alone or following their co-reconstitution (C) at pH 7.0 and 25°C, as described in Materials and Methods. The values reported are the means and standard deviations of triplicate measurements. For points with no error bar, the error was smaller than the symbol.
