The amino acid sequences of eleven tryptic peptides of papaya mosaic virus protein by electron ionization mass spectrometry.
Eleven of the fourteen tryptic peptides of papaya mosaic virus protein have been sequenced by electron ionization mass spectrometry using chemical and enzymic hydrolyses and mixture analysis as required. Mid-chain cleavages of N-C bonds produced secondary ion series which allowed up to 16 residues to be sequenced without further hydrolysis. Mixture analysis on hydrolysis products enabled a 24 residue tryptic peptide to be sequenced from the data recorded in a single mass spectrum.
