ttrR

Gene
ttrR
Protein
Tetrathionate response regulatory protein TtrR
Organism
Salmonella typhimurium (strain LT2 / SGSC1412 / ATCC 700720)
Length
206 amino acids
Function
Member of the two-component regulatory system TtrR/TtrS, which is required for synthesis of tetrathionate reductase. Positively regulates transcription of the ttrBCA operon. During mice infection, the ability to use tetrathionate as an electron acceptor is a growth advantage for S.typhimurium over the competing microbiota in the lumen of the inflamed gut.
