A heptamer that includes the tau and gamma products of the dnaX gene and the chi/psi subcomplex. Confers structural asymmetry that allows the polymerase to replicate both leading and lagging strands.
A dimer composed of the chi and psi subunits which is a subassembly of the DNA polymerase III clamp loader complex and serves as a bridge between the DnaX complex and the single-stranded DNA-binding protein (SSB).
