Non-hydrogen bond interactions involving the methionine sulfur atom.

Abstract

Of all the nonbonded interactions, hydrogen bond, because of its geometry involving polar atoms, is the most easily recognizable. Here we characterize two interactions involving the divalent sulfur of methionine (Met) residues that do not need any participation of proton. In one an oxygen atom of the main-chain carbonyl group or a carboxylate side chain is… (More)
