[[http://www.uniprot.org/uniprot/DPO3X_ECOLI DPO3X_ECOLI]] DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3' to 5' exonuclease activity.  Isoform tau: serves as a scaffold to help in the dimerization of the core complex.  Isoform gamma: seems to interact with the delta subunit. to transfer the beta subunit on the DNA. [[http://www.uniprot.org/uniprot/DPO3A_ECOLI DPO3A_ECOLI]] DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3' to 5' exonuclease activity. The alpha chain is the DNA polymerase. [[http://www.uniprot.org/uniprot/DPO3E_ECOLI DPO3E_ECOLI]] DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. The epsilon subunit contain the editing function and is a proofreading 3'-5' exonuclease. [[http://www.uniprot.org/uniprot/DPO3B_ECOLI DPO3B_ECOLI]] DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3' to 5' exonuclease activity. The beta chain is required for initiation of replication once it is clamped onto DNA, it slides freely (bidirectional and ATP-independent) along duplex DNA.
