DNA Sliding Clamps: Just the Right Twist to Load onto DNA [PDF]
Two recent papers illuminate a key step in DNA sliding clamp loading: one reveals the structure of the PCNA clamp wrapped around DNA--still open from being loaded--while the other finds that the clamp may assist this process by forming a right-handed helix upon opening.

Competition for the nascent leading strand shapes the requirements for PCNA loading in the replisome
During DNA replication, the DNA polymerases Pol δ and Pol ε utilise the ring-shaped sliding clamp PCNA to enhance their processivity. PCNA loading onto DNA is accomplished by the clamp loaders RFC and Ctf18-RFC, which function primarily on the lagging ...

Multiple C-Terminal Tails within a Single \u3cem\u3eE. coli\u3c/em\u3e SSB Homotetramer Coordinate DNA Replication and Repair [PDF]
Escherichia coli single-stranded DNA binding protein (SSB) plays essential roles in DNA replication, recombination and repair. SSB functions as a homotetramer with each subunit possessing a DNA binding domain (OB-fold) and an intrinsically disordered C ...
