A genetic screening for osmoregulated genes allowed us to identify the yfeR gene of Salmonella enterica serovar Typhimurium. The yfeR gene product encodes a novel LysR-type transcriptional regulator (LTTR), the expression of which decreases when external osmolarity increases. Out of the adjacent gene yfeH, YfeR modulates expression of several genes that may be required for optimal growth under low osmolarity conditions.
