The beta chain is required for initiation of replication as [...] (378 aa) | ||||
radA | DNA repair: sensitivity to gamma and UV radiation; Plays a role in repairing double-strand DNA breaks, probably involving stabilizing or processing branched DNA or blocked replication forks (By similarity). Required for efficient transformation with chromosomal (linear) DNA, but not for replicative plasmid DNA. Its increased sensitivity to a DNA damaging agent suggests it may be required for DNA repair. (420 aa) | ||||

(256 aa) | ||||
hexB | DNA mismatch repair protein; This protein is involved in the repair of mismatches in DNA. The hex system is nick-directed. (649 aa) | ||||
ruvA | Holliday junction DNA helicase; The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination.

uvrA | Excinuclease ABC - subunit A; The UvrABC repair system catalyzes the recognition and processing of DNA lesions. UvrA is an ATPase and a DNA-binding protein. A damage recognition complex composed of 2 UvrA and 2 UvrB subunits scans DNA for abnormalities. When the presence of a lesion has been verified by UvrB, the UvrA molecules dissociate. (943 aa) | ||||
ruvB | Branch migration of Holliday structures; The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is a helicase that mediates the Holliday junction migration by localized denaturation and reannealing. (332 aa) | ||||
polC | DNA polymerase III, alpha subunit; Required for replicative DNA synthesis. This DNA polymerase also exhibits 3' to 5' exonuclease activity. (1463 aa) | ||||
mutS2 | DNA mismatch repair protein; Endonuclease that is involved in the suppression of homologous recombination and may therefore have a key role in the control of bacterial genetic diversity; Belongs to the DNA mismatch repair MutS family. MutS2 subfamily. (778 aa) | ||||
dinP | DNA-damage-inducible protein P; Poorly processive, error-prone DNA polymerase involved in untargeted mutagenesis. Copies undamaged DNA at stalled replication forks, which arise in vivo from mismatched or misaligned primer ends. These misaligned primers can be extended by PolIV. Exhibits no 3'-5' exonuclease (proofreading) activity. May be involved in translesional synthesis, in conjunction with the beta clamp from PolIII. (356 aa) | ||||
recJ | Single-stranded DNA-specific exonuclease, 5'-3'. (744 aa) | ||||
uvrC | Exonuclease ABC - subunit C; The UvrABC repair system catalyzes the recognition and processing of DNA lesions. UvrC both incises the 5' and 3' sides of the lesion. The N-terminal half is responsible for the 3' incision and the C-terminal half is responsible for the 5' incision. (614 aa) | ||||
holA | DNA polymerase III, delta subunit. (345 aa) | ||||
dnaX | DNA-directed DNA polymerase III chain; DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3' to 5' exonuclease activity. (551 aa) | ||||
dnaE | DNA-polymerase III alpha-chain. (1042 aa) | ||||
holB | DNA polymerase III, delta' subunit. (296 aa) | ||||

AddB/RexB type 2 subfamily. (1091 aa) | ||||
rexA | First subunit of major exonuclease; The heterodimer acts as both an ATP-dependent DNA helicase and an ATP-dependent, dual-direction single-stranded exonuclease. Recognizes the chi site generating a DNA molecule suitable for the initiation of homologous recombination. The AddA nuclease domain is required for chi fragment generation; this subunit has the helicase and 3' -> 5' nuclease activities; Belongs to the helicase family. AddA subfamily. (1216 aa) | ||||
uvrB | Exonuclease ABC - subunit B; The UvrABC repair system catalyzes the recognition and processing of DNA lesions. A damage recognition complex composed of 2 UvrA and 2 UvrB subunits scans DNA for abnormalities. Upon binding of the UvrA(2)B(2) complex to a putative damaged site, the DNA wraps around one UvrB monomer. DNA wrap is dependent on ATP binding by UvrB and probably causes local melting of the DNA helix, facilitating insertion of UvrB beta-hairpin between the DNA strands. Then UvrB probes one DNA strand for the presence of a lesion. If a lesion is found the UvrA subunits dissociate [...] (662 aa) | ||||
recR | Recombination protein RecR; May play a role in DNA repair. It seems to be involved in an RecBC-independent recombinational process of DNA repair. It may act with RecF and RecO (By similarity).
