[[Category: jcsg]]
[https://www.uniprot.org/uniprot/Q9WYA0_THEMA Q9WYA0_THEMA] 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 (By similarity).[PIRNR:PIRNR000804]
