| | tig | Trigger factor; Involved in protein export. Acts as a chaperone by maintaining the newly synthesized protein in an open conformation. Functions as a peptidyl-prolyl cis-trans isomerase; Belongs to the FKBP-type PPIase family. Tig subfamily. (434 aa) |
| | KQN61762.1 | Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology. (108 aa) |

| | thrS | threonine--tRNA ligase; Catalyzes the attachment of threonine to tRNA(Thr) in a two- step reaction: L-threonine is first activated by ATP to form Thr-AMP and then transferred to the acceptor end of tRNA(Thr). (642 aa) |
| | KQN61853.1 | Translation initiation factor IF-3; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the IF-3 family. (116 aa) |
| | rpmI | 50S ribosomal protein L35; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the bacterial ribosomal protein bL35 family. (65 aa) |
| | rplT | 50S ribosomal protein L20; Binds directly to 23S ribosomal RNA and is necessary for the in vitro assembly process of the 50S ribosomal subunit. It is not involved in the protein synthesizing functions of that subunit. (118 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) |
| | rfaH | Transcriptional regulator; Enhances distal genes transcription elongation in a specialized subset of operons that encode extracytoplasmic components. RfaH is recruited into a multi-component RNA polymerase complex by the ops element, which is a short conserved DNA sequence located downstream of the main promoter of these operons. Once bound, RfaH suppresses pausing and inhibits Rho-dependent and intrinsic termination at a subset of sites. Termination signals are bypassed, which allows complete synthesis of long RNA chains. (163 aa) |
| | secE | Protein translocase subunit SecE; Essential subunit of the Sec protein translocation channel SecYEG. Clamps together the 2 halves of SecY. May contact the channel plug during translocation; Belongs to the SecE/SEC61-gamma family. (127 aa) |
| | nusG | Transcription antiterminator NusG; Participates in transcription elongation, termination and antitermination. In the absence of Rho, increases the rate of transcription elongation by the RNA polymerase (RNAP), probably by partially suppressing pausing. In the presence of Rho, modulates most Rho-dependent termination events by interacting with the RNAP to render the complex more susceptible to the termination activity of Rho. May be required to overcome a kinetic limitation of Rho to function at certain terminators. Also involved in ribosomal RNA transcriptional antitermination; Belongs [...] (181 aa) |
| | rplK | 50S ribosomal protein L11; Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors. (142 aa) |
| | rplA | 50S ribosomal protein L1; Binds directly to 23S rRNA. The L1 stalk is quite mobile in the ribosome, and is involved in E site tRNA release. (234 aa) |
| | rplJ | 50S ribosomal protein L10; Forms part of the ribosomal stalk, playing a central role in the interaction of the ribosome with GTP-bound translation factors. Belongs to the universal ribosomal protein uL10 family. (165 aa) |
| | rplL | 50S ribosomal protein L7/L12; Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors. Is thus essential for accurate translation; Belongs to the bacterial ribosomal protein bL12 family. (121 aa) |
| | rpoB | DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. (1342 aa) |
| | rpoC | DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. (1407 aa) |
