miaA | Delta(2)-isopentenylpyrophosphate tRNA-adenosine transferase; Catalyzes the transfer of a dimethylallyl group onto the adenine at position 37 in tRNAs that read codons beginning with uridine, leading to the formation of N6-(dimethylallyl)adenosine (i(6)A); Belongs to the IPP transferase family. (316 aa) | ||||
ttk | Putative transcriptional regulator; Required for nucleoid occlusion (NO) phenomenon, which prevents Z-ring formation and cell division over the nucleoid. Acts as a DNA-associated cell division inhibitor that binds simultaneously chromosomal DNA and FtsZ, and disrupts the assembly of FtsZ polymers. SlmA-DNA-binding sequences (SBS) are dispersed on non-Ter regions of the chromosome, preventing FtsZ polymerization at these regions. (212 aa) | ||||
rho | Transcription termination factor Rho; Facilitates transcription termination by a mechanism that involves Rho binding to the nascent RNA, activation of Rho's RNA- dependent ATPase activity, and release of the mRNA from the DNA template. (419 aa) | ||||
xerC | Site-specific recombinase; Site-specific tyrosine recombinase, which acts by catalyzing the cutting and rejoining of the recombining DNA molecules. Binds cooperatively to specific DNA consensus sequences that are separated from XerD binding sites by a short central region, forming the heterotetrameric XerC-XerD complex that recombines DNA substrates. The complex is essential to convert dimers of the bacterial chromosome into monomers to permit their segregation at cell division. It also contributes to the segregational stability of plasmids. In the complex XerC specifically exchanges t [...] (298 aa) | ||||
glnG | Response regulator for gln; 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) | ||||
cpxA | Histidine protein kinase; Probable sensor protein; acting on arcA; Code: T; COG: COG0642. (457 aa) | ||||
cpxR | Transcriptional regulator in 2-component system; Code: TK; COG: COG0745. (232 aa) | ||||
envZ | Protein histidine kinase/phosphatase sensor for OmpR; Modulates expression of ompF and ompC; Code: T; COG: COG0642. (450 aa) | ||||
ompR | Response regulator affecting transcription of ompC and ompF; Sensor, EnvZ; outer membrane protein synthesis; Code: TK; COG: COG0745. (239 aa) | ||||
shuT | Putative periplasmic binding protein; Code: P; COG: COG4558. (330 aa) | ||||
rpoN | RNA polymerase, sigma(54 or 60) factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (477 aa) | ||||
rpoD | RNA polymerase, sigma(70) factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth. (613 aa) | ||||
relA | (p)ppGpp synthetase I; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance. (744 aa) | ||||
rpoS | RNA polymerase, sigma S factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the master transcriptional regulator of the stationary phase and the general stress response. (330 aa) | ||||
csrA | Carbon storage regulator; A key translational regulator that binds mRNA to regulate translation initiation and/or mRNA stability. Mediates global changes in gene expression, shifting from rapid growth to stress survival by linking envelope stress, the stringent response and the catabolite repression systems. Usually binds in the 5'-UTR; binding at or near the Shine-Dalgarno sequence prevents ribosome-binding, repressing translation, binding elsewhere in the 5'-UTR can activate translation and/or stabilize the mRNA. Its function is antagonized by small RNA(s). (61 aa) | ||||
yfgA | Putative membrane protein; Cytoskeletal protein that is involved in cell-shape control through regulation of the length of the long axis. (337 aa) | ||||
ompC | Outer membrane protein 1b; Ib;c; Code: M; COG: COG3203; Belongs to the Gram-negative porin family. (375 aa) | ||||
tgt | tRNA-guanine transglycosylase; Catalyzes the base-exchange of a guanine (G) residue with the queuine precursor 7-aminomethyl-7-deazaguanine (PreQ1) at position 34 (anticodon wobble position) in tRNAs with GU(N) anticodons (tRNA-Asp, -Asn, -His and -Tyr). Catalysis occurs through a double-displacement mechanism. The nucleophile active site attacks the C1' of nucleotide 34 to detach the guanine base from the RNA, forming a covalent enzyme-RNA intermediate. The proton acceptor active site deprotonates the incoming PreQ1, allowing a nucleophilic attack on the C1' of the ribose to form the [...] (375 aa) | ||||
mesJ | Cell cycle protein; Ligates lysine onto the cytidine present at position 34 of the AUA codon-specific tRNA(Ile) that contains the anticodon CAU, in an ATP-dependent manner. Cytidine is converted to lysidine, thus changing the amino acid specificity of the tRNA from methionine to isoleucine. Belongs to the tRNA(Ile)-lysidine synthase family. (431 aa) | ||||
dksA | dnaK suppressor protein; Transcription factor that acts by binding directly to the RNA polymerase (RNAP). Required for negative regulation of rRNA expression and positive regulation of several amino acid biosynthesis promoters. Also required for regulation of fis expression. (151 aa) |
