DNA polymerase III, beta chain, N-terminal (IPR022634)

Short name: DNA_polIII_beta_N

Domain relationships



This entry describes the N-terminal domain of the beta chain of DNA polymerase III. This 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.
