SUMMARY
The structure of DNA polymerase III is debated, with Snustard and Simmons presenting a diagram that features the clamp loader (γ-δ complex) on one side, while Lehninger depicts it as centrally located. Both diagrams have limitations due to the challenges of imaging large multiprotein complexes, which often rely on cryo-electron microscopy studies for accurate representation. The Snustard and Simmons diagram is considered to provide a minimal and potentially more accurate depiction, while the Lehninger version requires more interpretative imagination. For comprehensive understanding, consulting cryo-EM studies is recommended.
