hydG | Response regulator in two-component reguatory system with HydH; Member of the two-component regulatory system ZraS/ZraR. When activated by ZraS it acts in conjunction with sigma-54 to regulate the expression of zraP. Positively autoregulates the expression of the zraSR operon (By similarity). (441 aa) | ||||
fhlA | Formate hydrogen-lyase transcriptional activator for fdhF, hyc and hyp operons; Required for induction of expression of the formate dehydrogenase H and hydrogenase-3 structural genes. (692 aa) | ||||
glnG | EBP family response regulator in two-component regulatory system with GlnL; Member of the two-component regulatory system NtrB/NtrC, which controls expression of the nitrogen-regulated (ntr) genes in response to nitrogen limitation. Phosphorylated NtrC binds directly to DNA and stimulates the formation of open promoter-sigma54-RNA polymerase complexes. (469 aa) | ||||
prpR | Regulator for prp operon (EBP family); Involved in the transcriptional regulation of the propionate catabolism operon. (541 aa) | ||||
ygaA | Putative EBP family regulator; Required for the expression of anaerobic nitric oxide (NO) reductase, acts as a transcriptional activator for at least the norVW operon. Activation also requires sigma-54. (506 aa) | ||||
STM0652 | Putative sigma-54 dependent transcriptional regulator; Similar to E. coli response regulator of ato, ornithine decarboxylase antizyme (sensor ATOS) (AAC75280.1); Blastp hit to AAC75280.1 (461 aa), 37% identity in aa 67 - 453. (642 aa) | ||||
tyrR | Transcriptional regulatory protein TyrR; Involved in transcriptional regulation of aromatic amino acid biosynthesis and transport. Modulates the expression of at least 8 unlinked operons. Seven of these operons are regulated in response to changes in the concentration of the three aromatic amino acids (phenylalanine, tyrosine and tryptophan). These amino acids are suggested to act as co-effectors which bind to the TyrR protein to form an active regulatory protein. In most cases TyrR causes negative regulation, but positive effects on the tyrP gene have been observed at high phenylalani [...] (513 aa) | ||||
pspF | Similar to E. coli psp operon transcriptional activator (AAC74385.1); Blastp hit to AAC74385.1 (330 aa), 86% identity in aa 6 - 330. (326 aa) | ||||
pgtA | Activator protein; Member of the two-component regulatory system PgtB/PgtA that regulates the inducible phosphoglycerate transport system. When activated by PgtB it acts in conjunction with sigma-54 as a transcriptional activator. (415 aa) | ||||
yfhA | EBP family; similar to E. coli putative 2-component transcriptional regulator (AAC75607.1); Blastp hit to AAC75607.1 (444 aa), 95% identity in aa 1 - 444. (445 aa) |
