MS/MS data for SIRV2gp26 coat protein captured by SIRV2 Hjr immunoprecipitation.

aA single MS spectral scan of a defined mass range may contain many distinct peaks, each with a characteristic mass/charge ratio – m/z. MS/MS spectra are the total number of peptide spectra generated by MS/MS from a single distinct peak observed in a MS spectrum which match the predicted in silico fragments from a translated database of the SIRV2 genome (accession number: NC_004086 [12]).bTotal number of unique spectra detected and assigned to one peptide.cSpectra were scored by Spectrum Mill and assigned a quality score based on peak match and quality. Matching spectra were associated with a peptide sequence. A total MS/MS score was generated by summing only the highest scoring MS/MS spectrum for each peptide.dPercent of identified peptide amino acids matching total protein amino acids sequence.eProtein accession number from translated SIRV2 genome; accession number: NC_004086 [12]).fProteins were annotated by BLAST similarity (e[24].gSIRV2gp26 peptide identified by mass spectrometry.hSIRV2gp26 amino acid sequence highlighting putative trypsin digestion sites (underlined) and peptide identified by mass spectrometry (bold).
