DNA topoisomerase TopA; 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 s [...]

ATP-dependent helicase RecQ; KEGG: npu:Npun_F0932 4.3e-215 ATP-dependent DNA helicase RecQ; K03654 ATP-dependent DNA helicase RecQ; Psort location: CytoplasmicMembrane, score: 8.46.

Replicative DNA helicase DnaB; Participates in initiation and elongation during chromosome replication; it exhibits DNA-dependent ATPase activity. Belongs to the helicase family. DnaB subfamily.

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.

Hypothetical protein; KEGG: ame:724599 0.20 similar to Chromodomain-helicase-DNA-binding protein CG3733-PA; K11367 chromodomain-helicase-DNA-binding protein 1; Psort location: Cytoplasmic, score: 8.96.

KEGG: ava:Ava_C0075 2.0e-226 DNA polymerase III beta subunit family protein K02338; Psort location: Cytoplasmic, score: 9.97.

DNA-directed DNA polymerase; Confers DNA tethering and processivity to DNA polymerases and other proteins. Acts as a clamp, forming a ring around DNA (a reaction catalyzed by the clamp-loading complex) which diffuses in an ATP- independent manner freely and bidirectionally along dsDNA. Initially characterized for its ability to contact the catalytic subunit of DNA polymerase III (Pol III), a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria; Pol III exhibits 3'-5' exonuclease proofreading activity. The beta chain is required for initiation of repl [...]
