New structural snapshots provide molecular insights into the mechanism of high fidelity DNA synthesis.

Abstract excerpt

Time-lapse X-ray crystallography allows visualization of intermediate structures during the DNA polymerase catalytic cycle. Employing time-lapse crystallography with human DNA polymerase β has recently allowed us to capture and solve novel intermediate structures that are not stable enough to be analyzed by traditional crystallography. The structures of these intermediates reveals exciting surprises about active...
