DNA polymerase β: Closing the gap between structure and function.

ABSTRACT: DNA polymerase (dpol) β has served as a model for structural, kinetic, and computational characterization of the DNA synthesis reaction. The laboratory directed by Samuel H. Wilson has utilized a multifunctional approach to analyze the function of this enzyme at the biological, chemical, and molecular levels for nearly 50 years. Over this time, it has become evident that correlating static crystallographic structures of dpol β with solution kinetic measurements is a daunting task. However, aided by computational and spectroscopic approaches, novel and unexpected insights have emerged. While dpols generally insert wrong nucleotides with similar poor efficiencies, their capacity to insert the right nucleotide depends on the identity of the dpol. Accordingly, the ability to choose right from
