Abstract

In this work, a domain motion dependent rate model is constructed for a comprehensive understanding of CRISPR Cas9 dynamics. Differences in cleavage efficiencies and off-target rates are essentially due to altered interaction inside Cas9:RNA:DNA complex with mutated residues. We applied pair correlation analysis to whole Cas9 protein sequences to unravel structural organization of proteins. With the valuable 3D structures from experiments and simulations, the roles of mutations are clarified to shed light on bacteria-phage co-evolution strategies.

Dr. Haibin Su is an Associate Professor at Department of Chemistry in The Hong Kong University of Science and Technology since 2018. He graduated from University of Stony Brook, while performing his thesis projects in Center for Data Intensive Computing at Brookhaven National Laboratory. Then he went to Caltech for his PostDoc prior to joining Nanyang Technological University in 2005. His research interest includes development and application of theoretical and computational physical science: i.e., quantum-mechanical and classical simulations and modeling of the structural, kinetic, and dynamic properties of complex functional systems, in particular emergent collective properties at multiple spatial and temporal scales.
