DNA-directed RNA polymerase alpha chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.

DNA-directed RNA polymerase beta' subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.

DNA-directed RNA polymerase omega chain; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.

Cyclic AMP receptor protein; Similar to Escherichia coli, Escherichia coli O6, Escherichia coli O157:H7, and Shigella flexneri catabolite gene activator Crp or Cap or Csm or b3357 or c4132 or z4718 or ecs4208 or sf3376 SWALL:CRP_ECOLI (SWALL:P03020) (210 aa) fasta scores: E(): 6.2e-78, 99.04% id in 210 aa, and to Pectobacterium carotovorum subsp. carotovorum CrP SWALL:Q8KJ23 (EMBL:AB090359) (210 aa) fasta scores: E(): 4.6e-78, 99.04% id in 210 aa, and to Erwinia chrysanthemi Crp regulatory protein CrP SWALL:O07097 (EMBL:X89443) (210 aa) fasta scores: E(): 7.2e-77, 97.14% id in 210 aa.

N utilization substance protein A; Participates in both transcription termination and antitermination.

Regulator of sigma D; Binds RpoD and negatively regulates RpoD-mediated transcription activation by preventing the interaction between the primary sigma factor RpoD with the catalytic core of the RNA polymerase and with promoter DNA. May be involved in replacement of the RNA polymerase sigma subunit from RpoD to RpoS during the transition from exponential growth to the stationary phase.

Preprotein translocase subunit; The central subunit of the protein translocation channel SecYEG. Consists of two halves formed by TMs 1-5 and 6-10. These two domains form a lateral gate at the front which open onto the bilayer between TMs 2 and 7, and are clamped together by SecE at the back. The channel is closed by both a pore ring composed of hydrophobic SecY resides and a short helix (helix 2A) on the extracellular side of the membrane which forms a plug. The plug probably moves laterally to allow the channel to open. The ring and the pore may move independently.

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.

DNA gyrase subunit B; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner.
