Fig. 4From: TetR-family transcription factors in Gram-negative bacteria: conservation, variation and implications for efflux-mediated antimicrobial resistanceBiological roles of TFTRs in Escherichia and Salmonella. Proportion of TFTRs predicted to regulate various processes in (a) Escherichia spp. and (b) Salmonella spp. Based on the function assigned from literature search (Table 1). Escherichia spp. have two additional TFTRs involved in regulating metabolism. No other differences between TFTR function in Escherichia and Salmonella were observedBack to article page
