CRYSTAL STRUCTURE OF A REPLICATION FORK DNA POLYMERASE EDITING COMPLEX AT 2.7 A RESOLUTION


Overview

We have solved the crystal structures of the bacteriophage RB69 sliding clamp, its complex with a peptide essential for DNA polymerase interactions, and the DNA polymerase complexed with primer-template DNA. The editing complex structure shows a partially melted duplex DNA exiting from the exonuclease domain at an unexpected angle and significant changes in the protein structure. The clamp complex shows the C-terminal 11 residues of polymerase bound in a hydrophobic pocket, and it allows docking of the editing and clamp structures together. The peptide binds to the sliding clamp at a position identical to that of a replication inhibitor peptide bound to PCNA, suggesting that the replication inhibitor protein p21CIP1 functions by competing with eukaryotic polymerases for the same binding pocket on the clamp.

About this Structure

1CLQ is a Single protein structure of sequence from Enterobacteria phage rb69. The following page contains interesting information on the relation of 1CLQ with [DNA Polymerase]. Full crystallographic information is available from OCA.
