DNA mismatch repair protein mutL; This protein is involved in the repair of mismatches in DNA. It is required for dam-dependent methyl-directed DNA mismatch repair. May act as a 'molecular matchmaker', a protein that promotes the formation of a stable complex between two or more DNA-binding proteins in an ATP-dependent manner without itself being part of a final effector complex.

COGs: COG1293 RNA-binding protein homologous to eukaryotic snRNP; InterPro IPR008616: IPR008532; KEGG: dge:Dgeo_1423 fibronectin-binding A-like protein; PFAM: Fibronectin-binding A, N-terminal; Domain of unknown function DUF814; SPTR: Fibronectin-binding A-like protein; PFAM: Domain of unknown function (DUF814); Fibronectin-binding protein A N-terminus (FbpA).

Transcription factor CarD; Couples transcription and DNA repair by recognizing RNA polymerase (RNAP) stalled at DNA lesions. Mediates ATP-dependent release of RNAP and its truncated transcript from the DNA, and recruitment of nucleotide excision repair machinery to the damaged site; In the C-terminal section; belongs to the helicase family. RecG subfamily.

PHP domain protein; COGs: COG1387 Histidinol phosphatase and related hydrolase of the PHP family; InterPro IPR004013: IPR002054: IPR003583: IPR003141; KEGG: ddr:Deide_07030 putative DNA polymerase, family X; PFAM: PHP, C-terminal; SMART: Polymerase/histidinol phosphatase, N-terminal; DNA-directed DNA polymerase X; Helix-hairpin-helix DNA-binding motif, class 1; SPTR: Putative DNA polymerase, family X; PFAM: PHP domain.

Ribosomal protein S4; One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the body of the 30S subunit.

Conserved hypothetical protein CHP00159; Catalyzes the condensation of 2 ATP molecules into cyclic di- AMP (c-di-AMP), a second messenger used to regulate differing processes in different bacteria.

DNA repair protein RadA; DNA-dependent ATPase involved in processing of recombination intermediates, plays a role in repairing DNA breaks. Stimulates the branch migration of RecA-mediated strand transfer reactions, allowing the 3' invading strand to extend heteroduplex DNA faster. Binds ssDNA in the presence of ADP but not other nucleotides, has ATPase activity that is stimulated by ssDNA and various branched DNA structures, but inhibited by SSB. Does not have RecA's homology-searching function.

Nuclease SbcCD, D subunit; SbcCD cleaves DNA hairpin structures. These structures can inhibit DNA replication and are intermediates in certain DNA recombination reactions. The complex acts as a 3'->5' double strand exonuclease that can open hairpins. It also has a 5' single-strand endonuclease activity; Belongs to the SbcD family.

DNA replication and repair protein recF; The RecF protein is involved in DNA metabolism; it is required for DNA replication and normal SOS inducibility. RecF binds preferentially to single-stranded, linear DNA. It also seems to bind ATP; Belongs to the RecF family.
