CommentDNA polymerase III delta (holA) and delta prime (holB) subunits are distinct proteins encoded by separate genes. The delta prime subunit (holB) exhibits sequence homology to the tau and gamma subunits (dnaX), but the delta subunit (holA) does not demonstrate this same homology with dnaX. 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.
