Conserved hypothetical protein; Identified by match to protein family HMM PF05331.

Periplasmic sensor signal transduction histidine kinase; Identified by match to protein family HMM PF00672; match to protein family HMM PF02518.

Conserved hypothetical protein; When present on multicopy plasmids confers increased resistance to fluoroquinolone antibiotics such as ciprofloxacin and sparfloxacin but not the quinolone nalidixic acid. Forms a structure that exhibits size, shape and electrostatic similarity to B-form DNA; it may bind to DNA gyrase which is postulated to protect it from fluoroquinolones (By similarity). Belongs to the pentapeptide repeat protein family.

Signal recognition particle-docking protein FtsY; Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Acts as a receptor for the complex formed by the signal recognition particle (SRP) and the ribosome-nascent chain (RNC).

Signal recognition particle protein; Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Binds to the hydrophobic signal sequence of the ribosome-nascent chain (RNC) as it emerges from the ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic membrane where it interacts with the SRP receptor FtsY. Belongs to the GTP-binding SRP family. SRP54 subfamily.

Cation ABC transporter, ATP-binding protein, putative; Identified by match to protein family HMM PF00005.

ATPase.

Ribosomal protein L30; Identified by match to protein family HMM PF00327; match to protein family HMM TIGR01308.

Ribosomal protein L18; This is one of the proteins that binds and probably mediates the attachment of the 5S RNA into the large ribosomal subunit, where it forms part of the central protuberance.
