Functional redundancy revealed by the deletion of the mimivirus GMC-oxidoreductase genes

J.-M. Alempic, H. Bisio, A. Villalta, S. Santini, A. Lartigue, A. Schmitt, C. Bugnot, A. Notaro, L. BELMUDES, A. Adrait, O. Poirot, D. Ptchelkine, C. De Castro, Y. Coute, C. Abergel

The study shows that deleting GMC-oxidoreductase genes in mimiviruses does not impair genomic fiber or fibril layer formation, indicating functional redundancy.

Interaction of HelQ helicase with RPA modulates RPA-DNA binding and stimulates HelQ to unwind DNA through a protein roadblock.

S. J. Northall, T. Jenkins, D. Ptchelkine, V. Taresco, C. Cooper, P. Soultanas, E. Bolt

This study identifies HelQ helicase's interaction with RPA, showing it enhances DNA unwinding through protein barriers but not abasic sites by destabilizing RPA-DNA binding.
