Title: Selective dansylation of M protein within intact influenza virions

Journal Article · · J. Virol.; (United States)
OSTI ID:6149455

Exposure of purified influenza virions to (/sup 14/C)dansyl chloride resulted in the covalent attachment of the dansyl chromophore to the virion. Gel electrophoresis revealed that the dansyl chromophore was specifically coupled to the internal membrane (M) protein. Purification of the M protein by gel filtration followed by cyanogen bromide cleavage and peptide fractionation revealed that four of six peptide peaks contained dansyl label. Acid hydrolysis of the separated peptide peaks followed by thin-layer chromatography revealed that dansyl label was coupled to lysine residues present in these peptides. The results of these investigations have demonstrated that the M protein molecule is the major viral polypeptide labeled when intact virions are exposed to dansyl chloride.
