enzymes has been designed via rational mutagenesis utilizing in silico docking, molecular dynamics, and structural nuclear magneticresonance (NMR) studies. The mutant enzyme MsrA33 was found to catalyze the kinetic resolution of bulky sulfoxide substrates bearing non-methyl substituents on the sulfur atom with ees up to 99%, overcoming a significant limitation of the currently available MsrA biocatalysts
