CC -!- FUNCTION: DNA polymerase III is a complex, multichain enzyme
CC responsible for most of the replicative synthesis in bacteria. The
CC epsilon subunit contain the editing function and is a proofreading 3'-
CC 5' exonuclease. {ECO:0000256|RuleBase:RU364087}.
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 -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000256|ARBA:ARBA00001936,
CC ECO:0000256|RuleBase:RU364087};
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
CC complex. {ECO:0000256|RuleBase:RU364087}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:KRG66565.1}.
