CC -!- FUNCTION: Confers DNA tethering and processivity to DNA polymerases and
CC other proteins. Acts as a clamp, forming a ring around DNA (a reaction
CC catalyzed by the clamp-loading complex) which diffuses in an ATP-
CC independent manner freely and bidirectionally along dsDNA. Initially
CC characterized for its ability to contact the catalytic subunit of DNA
CC polymerase III (Pol III), a complex, multichain enzyme responsible for
CC most of 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|ARBA:ARBA00004496,
CC ECO:0000256|PIRNR:PIRNR000804}.
CC -!- SIMILARITY: Belongs to the beta sliding clamp family.
CC {ECO:0000256|ARBA:ARBA00010752, ECO:0000256|PIRNR:PIRNR000804}.
