    Ramos,. The position of rPruR is indicated by an arrowhead. This possibility is currently being investigated by our group. Materials and Methods Ethics Statement All animal studies complied with

    National and Nankai University guidelines regarding the use of animals in research. Bacterial cells were harvested by centrifugation and adjusted to 2 109 CFU/ml in sterile 1 PBS (274 mM NaCl,.4 mM KCl BBI life sciences, 20 mM Na2HPO4, 4 mM KH2PO4,.4). Regulation of flavin dehydrogenase compartmentalization: requirements for PutA-membrane association in Salmonella typhimurium. Under oxidative stress, proline utilization by PutA changes bacterial intracellular redox condition, which activates OxyR, leading to increased expression of katG, grxA, and trxC ( Zhang., 2015 ). Indicated strains were cultured in (A) LB broth or (B) MMP medium containing.0 (w/v) glucose and.1 (w/v) (NH4)2SO4 at 37C. p.01, compared to the wild type PAK strain or the putA / putA complemented strain by log-rank (Mantel-Cox) test. The p53-induced baila gene-6 (proline oxidase) mediates apoptosis through a calcineurin-dependent pathway. The role of proline in osmoregulation in Salmonella typhimurium and Escherichia coli. Conflict of Interest Statement The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. The data were from 13 mice per strain. Amino Acids 35, 711718. High concentration of proline in bacteria up-regulates pruR expression. Survival rate of the putA mutant strain was significantly lower than that of wild type PAK strain (Figure 3 ). Enzymatic properties of the purified putA protein from Salmonella typhimurium. In Agrobacterium tumefaciens and Rhodobacter capsulatus, the expression of putA is trans-activated by a Lrp-family protein, called PutR ( Keuntje., 1995 ; Cho and Winans, 1996 ).

H., and Schweizer,. The expression of pruR and putA was highly up-regulated in MMP medium supplemented with 25 tarzan mM proline, but did not show significant changes in MMP medium supplemented with 25 mM glutamate (Figure 6E ). Regulation of proline utilization in Salmonella typhimurium : molecular characterization of the put operon, and DNA sequence of the put control region. Construction of lacZ Fusions For reporter assay.

Plasmids used in this study are listed in Table. The amplified fragment was digested with restriction enzymes and ligated into the same restriction enzymedigested pET28a. D emsa for dosedependent effects of proline and glutamate on the binding of PruR to the putA promoter 1099mic 0, jiang, the wild type PAK strain was cultured in MMP medium supplemented with different concentrations of proline at 37C for overnight. H Doi, sun, atkinson, interestingly PruR binding was affected by glutamate concentration. Also we found that PruR is not autoregulated.
