Protein Family Models

DNA polymerase III, delta subunit (EC 2.7.7.7) is required for, along with delta' subunit, the assembly of the processivity factor beta(2) onto primed DNA in the DNA polymerase III holoenzyme-catalysed reaction [1]. The delta subunit is also known as HolA. [1]. 11432857. The delta and delta ' subunits of the DNA polymerase III holoenzyme are essential for initiation complex formation and processive elongation.

DNA polymerase III subunit delta' interacts with the delta and gamma subunits and is part of the clamp-loading complex, which assembles the beta processivity factor onto the primer template and plays a central role in the organization and communication at the replication fork

Catalyzes the DNA-template-directed extension of the 3'-end of a DNA strand; the delta' subunit seems to interact with the gamma subunit to transfer the beta subunit on the DNA
