CC   -!- FUNCTION: Confers DNA tethering and processivity to DNA
CC       polymerases and other proteins. Acts as a clamp, forming a ring
CC       around DNA (a reaction catalyzed by the clamp-loading complex)
CC       which diffuses in an ATP-independent manner freely and
CC       bidirectionally along dsDNA. Initially characterized for its
CC       ability to contact the catalytic subunit of DNA polymerase III
CC       (Pol III), a complex, multichain enzyme responsible for most of
CC       the replicative synthesis in bacteria; Pol III exhibits 3'-5'
CC       exonuclease proofreading activity. The beta chain is required for
CC       initiation of replication as well as for processivity of DNA
CC       replication. {ECO:0000256|PIRNR:PIRNR000804}.
CC   -!- SUBUNIT: Forms a ring-shaped head-to-tail homodimer around DNA.
CC       {ECO:0000256|PIRNR:PIRNR000804}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|PIRNR:PIRNR000804,
CC       ECO:0000256|SAAS:SAAS00729396}.
CC   -!- SIMILARITY: Belongs to the beta sliding clamp family.
