Role of Active Site Residues in Promoting Cobalt-Carbon Bond Homolysis in Adenosylcobalamin-Dependent Mutases Revealed Through Experiment and Computation

Adenosylcobalamin serves as a source of reactive free radicals that are generated by homolytic scission of the coenzyme’s cobalt-carbon bond. AdoCbl-dependent enzymes accelerate AdoCbl homolysis by ~10(12)-fold, but the mechanism by which this is accomplished remains unclear. We have combined experi...
