Trapping and Electron Paramagnetic Resonance Characterization of the 5′dAdo(•) Radical in a Radical S-Adenosyl Methionine Enzyme Reaction with a Non-Native Substrate

[Image: see text] S-Adenosyl methionine (SAM) is employed as a [4Fe-4S]-bound cofactor in the superfamily of radical SAM (rSAM) enzymes, in which one-electron reduction of the [4Fe-4S]-SAM moiety leads to homolytic cleavage of the S-adenosyl methionine to generate the 5′-deoxyadenosyl radical (5′dAd...
