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 delta (holA) and delta-prime (holB) subunits are distinct proteins encoded by separate genes. The delta, delta-prime, gamma, chi and psi subunits form the gamma complex subassembly of DNA polymerase III holoenzyme, which couples ATP to assemble the ring-shaped beta subunit around DNA forming a DNA sliding clamp.

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, plays a central role in the organization and communication at the replication fork and present in initiation complex which is required for processive elongation.
