Fig. 1 MALDI-TOF mass spectra of tryptic peptides released from FHV and FHV VLPs. a, v-WT-d particles containing viral RNA; b, r-WT-b particles containing cellular RNA. γf: tryptic peptides from the cleavage of γ-peptide. βf: tryptic peptides from cleavage of the major coat protein β. int. std.: a synthetic version of the γ-peptide consisting of the N-terminal 21 amino acids (mw 2,242 Da). A dramatic difference in the rate of digestion between particles packaging viral versus cellular RNA is observed based on the higher concentration (17-fold) of tryptic fragments seen in (b). The γ-peptide is a 44 amino acid peptide (mw 4,396 Da) resulting from the autocatalytic cleavage of the coat precursor protein. c, A bar graph showing the influence of RNA on capsid dynamics: FHV particles containing viral RNA exhibit less dynamic motion than particles containing random cellular RNA. The rate of proteolysis is related to enzyme accessibility and is therefore a function of capsid dynamics. Particle types v-WT-d and v-D75N-d, the only particles that contain viral RNA, are significantly more stable than all other types tested. a b c
