Therefore , this enzyme activity would be another determinant for the RstAcontrolled iron response in Salmonella and also a reason that expression of the E. coli feoB gene from plasmid results in equally enhanced Fe ( II ) uptake in cells grown aerobically or anaerobically ( 12 ) .
This result was correlated with regulation of the feoB gene in response to RstA activation : in the wild-type strain , iron decreased feoB transcription whereas RstA expression highly increased it .
