Samuel H. Wilson heads the DNA Repair and Nucleic Acid Enzymology Group and holds a secondary appointment in the NIEHS Epigenetics and Stem Cell Biology Laboratory. The DNA Repair & Nucleic Acid Enzymology Group has made a number of contributions over the years to the understanding of mechanisms of DNA synthesis and, in particular, synthesis by the repair enzyme DNA polymerase β (Pol β). They identified the kinetic mechanism of this enzyme, its primary and 3 dimensional structures, and its biological roles in base excision DNA repair. This DNA repair pathway protects cells against endogenous DNA lesion including single-strand breaks.
