Endonuclease; Structure-specific nuclease with 5'-flap endonuclease and 5'- 3' exonuclease activities involved in DNA replication and repair. During DNA replication, cleaves the 5'-overhanging flap structure that is generated by displacement synthesis when DNA polymerase encounters the 5'-end of a downstream Okazaki fragment. Binds the unpaired 3'-DNA end and kinks the DNA to facilitate 5' cleavage specificity. Cleaves one nucleotide into the double-stranded DNA from the junction in flap DNA, leaving a nick for ligation. Also involved in the base excision repair (BER) pathway. Acts as [...]

Replication protein A protects and stabilize the intermediate ssDNA that is generated by the unwinding action of a DNA helicase at the replication fork. In addition, SSBs prevent the formation of secondary structures by single-stranded template DNA; Derived by automated computational analysis using gene prediction method: Protein Homology.

NADH-quinone oxidoreductase subunit C; Derived by automated computational analysis using gene prediction method: Protein Homology.

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.

ATPase; Originally found to be an inhibitor of the antiviral RNase-L in human cells; contains ABC-type nucleotide binding domains; putatively functions in RNA maturation; Derived by automated computational analysis using gene prediction method: Protein Homology.

Preprotein translocase subunit SecY; The central subunit of the protein translocation channel SecYEG. Consists of two halves formed by TMs 1-5 and 6-10. These two domains form a lateral gate at the front which open onto the bilayer between TMs 2 and 7, and are clamped together by SecE at the back. The channel is closed by both a pore ring composed of hydrophobic SecY resides and a short helix (helix 2A) on the extracellular side of the membrane which forms a plug. The plug probably moves laterally to allow the channel to open. The ring and the pore may move independently.

30S ribosomal protein S4; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the eukaryotic ribosomal protein eS4 family.

Metallophosphatase; Part of the Rad50/Mre11 complex, which is involved in the early steps of DNA double-strand break (DSB) repair. 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.

DNA polymerase IV; 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.
