摘要：

The Escherichia coli OxyR protein is a transcriptional activator for a number of genes induced in response to low concentrations of hydrogen peroxide. To identify additional OxyR-regulated genes, I cloned a DNA fragment that shows promoter activity regulated by OxyR by direct selection of OxyR-binding DNA fragments, Analyses of the cloned fragment indicate that the gm gene, encoding glutaredoxin 1, is inducible by hydrogen peroxide in an oxyR-dependent fashion.
