CC   -!- FUNCTION: DNA polymerase III is a complex, multichain enzyme
CC       responsible for most of the replicative synthesis in bacteria. This DNA
CC       polymerase also exhibits 3' to 5' exonuclease activity. The alpha chain
CC       is the DNA polymerase (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a 2'-deoxyribonucleoside 5'-triphosphate + DNA(n) =
CC         diphosphate + DNA(n+1); Xref=Rhea:RHEA:22508, Rhea:RHEA-COMP:17339,
CC         Rhea:RHEA-COMP:17340, ChEBI:CHEBI:33019, ChEBI:CHEBI:61560,
CC         ChEBI:CHEBI:173112; EC=2.7.7.7;
CC   -!- SUBUNIT: DNA polymerase III contains a core (composed of alpha, epsilon
CC       and theta chains) that associates with a tau subunit. This core
CC       dimerizes to form the PolIII' complex. PolIII' associates with the
CC       gamma complex (composed of gamma, delta, delta', psi and chi chains)
CC       and with the beta chain to form the complete DNA polymerase III complex
CC       (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the DNA polymerase type-C family. DnaE
CC       subfamily. {ECO:0000305}.
