New paper out! We show that RecBC remodels single-stranded DNA gaps to protect them from ExoI (sbcB) 3′-5′ exonuclease degradation during replication of damaged DNA.

Our key findings:
-DNA polymerase η swiftly bypasses UV-induced lesions at the replication fork.
-Post-replicative gaps allow Translesion Synthesis (TLS) to compete with Damage Avoidance (DA), reducing mutagenicity.
-Gap extension by Exo1 nuclease favors DA and reduces TLS
Our latest article, in collaboration with Helle Ulrich, explores how the timing of lesion bypass and gap processing impacts genome stability.

How does Pol IV overcome strong replication blocks in E. coli? Our latest study with @JoeLoparo uncovers a bipartite clamp interaction that helps Pol IV compete with Pol III, enabling efficient TLS at stalled forks and reducing mutagenesis.

New review article, written by Lewis Bainbridge @LewisBainb53268 and me. This article
focuses on the diverse roles of replicative DNA polymerases during genome replication and their molecular basis.
