DNA polymerase sliding clamp; Sliding clamp subunit that acts as a moving platform for DNA processing. Responsible for tethering the catalytic subunit of DNA polymerase and other proteins to DNA during high-speed replication.

DNA repair and recombination protein radA; Involved in DNA repair and in homologous recombination. Binds and assemble on single-stranded DNA to form a nucleoprotein filament. Hydrolyzes ATP in a ssDNA-dependent manner and promotes DNA strand exchange between homologous DNA molecules.

Metallophosphoesterase; Part of the Rad50/Mre11 complex, which is involved in the early steps of DNA double-strand break (DSB) repair. The complex may facilitate opening of the processed DNA ends to aid in the recruitment of HerA and NurA. Mre11 binds to DSB ends and has both double-stranded 3'-5' exonuclease activity and single-stranded endonuclease activity. Belongs to the MRE11/RAD32 family.

Helicase domain protein; KEGG: mth:MTH1415 Hef nuclease; PFAM: Helicase, C-terminal; DNA/RNA helicase, DEAD/DEAH box type, N-terminal; ERCC4 domain; Helix-hairpin-helix motif; SMART: DEAD-like helicase, N-terminal; Helicase, C-terminal; ERCC4 domain; Helix-hairpin-helix DNA-binding motif, class 1.

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 [...]

Replication factor C large subunit; Part of the RFC clamp loader complex which loads the PCNA sliding clamp onto DNA; Belongs to the activator 1 small subunits family. RfcL subfamily.

DNA repair and recombination protein radB; Involved in DNA repair and in homologous recombination. May regulate the cleavage reactions of the branch-structured DNA. Has a very weak ATPase activity that is not stimulated by DNA. Binds DNA but does not promote DNA strands exchange.

DNA primase small subunit; Catalytic subunit of DNA primase, an RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. The small subunit contains the primase catalytic core and has DNA synthesis activity on its own. Binding to the large subunit stabilizes and modulates the activity, increasing the rate of DNA synthesis while decreasing the length of the DNA fragments, and conferring RNA synthesis capability. The DNA polymerase activity may enable DNA primase to also catalyze primer extension after primer synthesis. [...]

KEGG: mmg:MTBMA_c15860 DNA polymerase; PFAM: DNA-directed DNA polymerase, family B, conserved region; DNA-directed DNA polymerase, family B, exonuclease domain; SMART: DNA-directed DNA polymerase, family B.
