Protein
HTH-type transcriptional repressor NsrR
Organism
Salmonella typhimurium (strain LT2 / SGSC1412 / ATCC 700720)
Function
Nitric oxide-sensitive repressor of genes involved in protecting the cell against nitrosative stress. May require iron for activity. Represses hmp expression under conditions of elevated intracellular iron concentrations, in the absence of nitric oxide.
