THERMODYNAMIC AND KINETIC PROPERTIES OF CYTOCHROMES C AND C’ IN THE DENATURED STATE: PROPENSITY FOR RESIDUAL STRUCTURE
… loops that contain the A83S/A87S substitutions. Kinetic data shows nonrandom behavior in the denatured state similar to pWT, and also supports the suggestion of helical propensity only being important if the helical segment is contained within the loop, as kf values are slightly faster for loops …

DNA and Ligand Binding and Kinetic Properties of Wild-Type and Mutant RsrI [n6-Adenine] DNA Methyltransferases
To complement the biochemical characterization of M•Rsr I in vitro, DNA binding analysis in vivo was performed using the bacteriophage P22-based challenge-phage assay. I isolated a catalytically impaired mutant, M•RsrI (L72P), that, unlike wild-type M•RsrI, binds in a …

An off-lattice kinetic Monte Carlo method for the investigation of grain boundary kinetic processes
Kinetic Monte Carlo (Kc) methods have the potential to extend the accessible timescales of off-lattice atomistic simulations beyond the limits of molecular dynamics by making use of transition state theory and parallelization. However, it is a challenge to identify a complete catalog of events …
