Cross-dressing proteins by olefin metathesis

Chemists have established numerous methods for performing protein conjugations, but metathesis catalysts have largely remained absent from this toolkit. Evidence that proteins bearing allylsulfides undergo cross-metathesis with chosen alkenes in aqueous conditions will allow chemists to harness the power of metathesis catalysts for modifying biomolecules and other water-soluble compounds.
