Protein
HTH-type transcriptional regulator YjiE
Organism
Escherichia coli (strain K12)
Function
Protects cells from HOCl (hypochlorite) stress but not peroxide or diamide stress. Decreases the intracellular load of reactive oxygen species by up-regulating genes involved in methionine and cysteine biosynthesis and down-regulating Fur-regulated genes involved in iron acquisition. Has also been suggested to down-regulate expression of the flagellar regulon, decreasing motility, but this activity was not confirmed in a second study (PubMed:22223481).
Similarity
Belongs to the LysR transcriptional regulatory family.
