| UniProt functional annotation for J1IY24 | |||
| UniProt code: J1IY24. |
| Organism: | Bartonella birtlesii LL-WM9. | |
| Taxonomy: | Bacteria; Proteobacteria; Alphaproteobacteria; Rhizobiales; Bartonellaceae; Bartonella. | |
| Function: | 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 replication as well as for processivity of DNA replication. {ECO:0000256|PIRNR:PIRNR000804}. | |
| Subunit: | Forms a ring-shaped head-to-tail homodimer around DNA. {ECO:0000256|PIRNR:PIRNR000804}. | |
| Subcellular location: | Cytoplasm {ECO:0000256|ARBA:ARBA00004496, ECO:0000256|PIRNR:PIRNR000804}. | |
| Similarity: | Belongs to the beta sliding clamp family. {ECO:0000256|ARBA:ARBA00010752, ECO:0000256|PIRNR:PIRNR000804}. | |
