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.

Segregation and condensation protein B; Participates in chromosomal partition during cell division. May act via the formation of a condensin-like complex containing Smc and ScpA that pull DNA away from mid-cell into both cell halves.

Helix-turn-helix protein, YlxM/p13 family; Might take part in the signal recognition particle (SRP) pathway. This is inferred from the conservation of its genetic proximity to ftsY/ffh. May be a regulatory protein.

Xanthine phosphoribosyltransferase; Converts the preformed base xanthine, a product of nucleic acid breakdown, to xanthosine 5'-monophosphate (XMP), so it can be reused for RNA or DNA synthesis.

ATPase/histidine kinase/DNA gyrase B/HSP90 domain protein; KEGG: btk:BT9727_3012 6.8e-62 sensor histidine kinase; COG: COG0642 Signal transduction histidine kinase; Psort location: CytoplasmicMembrane, score: 9.70.

Response regulator receiver domain protein; KEGG: eci:UTI89_C0420 1.9e-41 phoB; positive response regulator for pho regulon K07657; COG: COG0745 Response regulators consisting of a CheY-like receiver domain and a winged-helix DNA-binding domain; Psort location: Cytoplasmic, score: 9.98.

Putative TIGR02678 family protein; COG: NOG16830 non supervised orthologous group; Psort location: CytoplasmicMembrane, score: 7.80.

DNA topoisomerase I; Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA- (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing DNA supe [...]
