Areas of Interest
My current research project is focused on elucidating interactions between human DNA ligase I (LIG1) and its substrate DNA using both structural and kinetic techniques. LIG1 is the main replicative DNA ligase in eukaryotes and is required for normal cell growth. Currently, I am characterizing active site mutants of LIG1 and analyzing the effects of perturbations of its ability to perform specific steps of its catalytic mechanism. I hope to follow this with using X-ray crystallography to gain structural insights into the interactions between LIG1 and a nicked-DNA substrate, which will hopefully enhance our understanding of how LIG1 is able to identify a nicked-DNA substrate for catalysis.
