DNA polymerase III beta subunit
SMART accession number:SM00480
Interpro abstract (IPR001001): DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. The beta chain is required for initiation of replication from an RNA primer, nucleotide triphosphate (dNTP) residues being added to the 5'-end of the growing DNA chain.
GO process:DNA replication (GO:0006260)
GO component:DNA polymerase III complex (GO:0009360)
GO function:3'-5' exonuclease activity (GO:0008408), DNA-directed DNA polymerase activity (GO:0003887), DNA binding (GO:0003677)
Family alignment:
