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 [...]

DNA polymerase III delta subunit. 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. The delta subunit seems to interact with the gamma subunit to transfer the beta subunit on the DNA; High confidence in function and specificity.

Putative DNA polymerase III chi subunit, 40% Identity to TrEMBL; Q8XWQ9,Q63WC2,Q62LH1. Has PF04364, DNA polymerase III chi subunit, HolC;IPR007459, DNA_pol3_chi; The DNA polymerase III holoenzyme is the polymerase responsible for the replication of the Escherichia coli chromosome. The holoenzyme is composed of the DNA polymerase III core, the sliding clamp, and the DnaX clamp loading complex. The DnaX complex contains either either the tau or gamma product of gene dnax, complexed to delta.delta' and to chi psi. Chi forms a 1:1 heterodimer with psi. The chi psi complex functions by incr [...]

Single-strand DNA-binding protein; 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.

DNA-directed DNA polymerase; DNA polymerase III alpha subunit. 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. THE ALPHA CHAIN IS THE DNA POLYMERASE (BY SIMILARITY). InterPro: DNA polymerase III alpha subunit TIGRFAM: polc: DNA polymerase III alpha subunit; High confidence in function and specificity.

DNA-directed DNA polymerase; 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.

DnaB protein; Participates in initiation and elongation during chromosome replication; it exhibits DNA-dependent ATPase activity and contains distinct active sites for ATP binding, DNA binding, and interaction with DnaC protein, primase, and other prepriming proteins. Belongs to the helicase family. DnaB subfamily.

DNA polymerase III, alpha subunit, putative; DNA polymerase involved in damage-induced mutagenesis and translesion synthesis (TLS). It is not the major replicative DNA polymerase.
