Establishing the allosteric mechanism in CRISPR‐Cas9
PublicationAllostery is a fundamental property of proteins, which regulates biochemical information transfer between spatially distant sites. Here, we report on the critical role of molecular dynamics (MD) simulations in discovering the mechanism of allosteric communication within CRISPR‐Cas9, a leading genome editing machinery with enormous promises for medicine and biotechnology. MD revealed how allostery intervenes during at least three...

Principles of target DNA cleavage and the role of Mg2+ in the catalysis of CRISPR–Cas9
PublicationAt the core of the CRISPR–Cas9 genome-editing technology, the endonuclease Cas9 introduces site-specific breaks in DNA. However, precise mechanistic information to ameliorate Cas9 function is still missing. Here, multimicrosecond molecular dynamics, free energy and multiscale simulations are combined with solution NMR and DNA cleavage experiments to resolve the catalytic mechanism of target DNA cleavage. We show that the conformation...

Catalytic Mechanism of Non-Target DNA Cleavage in CRISPR-Cas9 Revealed by Ab Initio Molecular Dynamics
PublicationCRISPR-Cas9 is a cutting-edge genome editing technology, which uses the endonuclease Cas9 to introduce mutations at desired sites of the genome. This revolutionary tool is promising to treat a myriad of human genetic diseases. Nevertheless, the molecular basis of DNA cleavage, which is a fundamental step for genome editing, has not been established. Here, quantum–classical molecular dynamics (MD) and free energy methods are used...

Boiling crisis - danger or a must?
PublicationW artykule przedstawiono zjawisko kryzysu wrzenia w przepływie. W głównej mierze skupiono się na zjawisku dryout'u podczas przepływu pierścieniowego. W pracy przedstawiono teoretyczny model wysychania filmu cieczowego na ściance wraz z jego modyfikacją w oparciu o model dwurównaniowy zaprezentowany przez Sedlera i Mikielewicza (1981). Model ten opiera się na bilansie cieczy w rdzeniu przepływu i w filmie cieczowym, gdzie głównym...
