General description
Ethly vinyl sulfone alkylates ε-amino groups of lysine side chains and imidazole groups of histidine residues in proteins. Chemical modification of bovine serum albumin by ethyl vinyl sulfone has been studied by X-ray photoelectron spectroscopy.

Ethly vinyl sulfone (EVS) alkylates xi-amino groups of lysine side chains and imidazole groups of histidine residues in proteins. Amino acid analysis of hydrolyzates of EVS-treated polylysine shows that lysine forms two derivatives, presumably xi-N-(ethylsulfonylethyl)lysine and xi, xi, N,N-bis(ethylsulfonylethyl)lysine that

Disulfide bonds of bovine serum albumin and wool were reduced by n-tributylphosphine to sulfhydryl groups that were then modified by methyl or ethyl vinyl sulfone in a nucleophilic addition reaction to S-(beta-ethylsulfonylmethyl)-L-cysteine and S(beta-ethylsulfonylethyl)-L-cysteine, respectively. The reductive alkylation was carried
