Abstract

The presence of an acetyl blocking group at theN-terminus of the coat protein of papaya mosaic virus has been identified by FAB mass spectrometry. Furthermore, we have found that theN-terminal sequence of the protein is four amino-acid residues (AC-Ser-Lys-Ser-Ser-) longer than that previously reported, while Glu instead of Gln is theC-terminal residue. The present paper shows that PMV-protein is made up of 215 amino acid residues, with a molecular mass of 22,960 Da.
