摘要
YdeO, an AraC-type transcription factor, is an important regulator in the induction of acid-resistance genes in Escherichia coli. In this study, we found that ydeO expression was induced 20 min after exposure to UV irradiation. This required the evgA and gadE genes in vivo. YdeO, induced by UV, controls the expression of a total of 21 genes. This accompanies SOS response in E. coli.
