Putative efflux transporter; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter.

Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.

K+-transporting ATPase; Integral membrane subunit of the KtrCD potassium uptake transporter. The 2 major potassium transporter complexes KtrAB and KtrCD confer resistance to both suddenly imposed and prolonged osmotic stress; Belongs to the TrkH potassium transport family. Ktr (TC 2.A.38.4) subfamily.

Cell-division protein and general stress protein (class III heat-shock); Acts as a processive, ATP-dependent zinc metallopeptidase for both cytoplasmic and membrane proteins. Plays a role in the quality control of integral membrane proteins; In the central section; belongs to the AAA ATPase family.

Putative paralog of RsbR; Evidence 7: Gene remnant; Product type pr: putative regulator.

Putative integral inner membrane protein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pm: putative membrane component.

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.

Transcription antitermination factor; Participates in transcription elongation, termination and antitermination. Stimulates RNA polymerase pausing at U107 and U144 in the trp leader. NusG-stimulated pausing is sequence specific. Does not affect trp leader termination.
