DNA polymerase III beta subunit DnaN; 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 initiatio [...]

DNA polymerase III epsilon subunit DnaQ; DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. The epsilon subunit contain the editing function and is a proofreading 3'- 5' exonuclease.

DNA polymerase III delta subunit HolA.

DNA polymerase III delta' subunit HolB.

DNA polymerase III chi subunit HolC.

Exonuclease.

Single-strand binding protein Ssb; Plays an important role in DNA replication, recombination and repair. Binds to ssDNA and to an array of partner proteins to recruit them to their sites of action during DNA metabolism.

Exonuclease family protein.

DNA-directed RNA polymerase beta subunit RpoB; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
