Figure S1. Mass-Spectrometric Identification (Peptide Mass Fingerprinting) of Bgdnv VP1

Figure S1. Mass-spectrometric identification (peptide mass fingerprinting) of BgDNV VP1. (A) MALDI-TOF spectrum of the trypsin-digested VP1 band with molecular weight corresponding to that predicted for the largest capsid protein, translated from the spliced VPSpl1 transcript. (B) List of mass/charge (m/z) values for peptide ions detected in the course of mass-spectrometric analysis. (C) The obtained m/z values were analyzed using Mascot Search software ( and peptide matches to the respective virus ORFs are indicated in the amino acid sequence with red color. The peptide matches are superimposed on the joined ORF translated from the spliced VPSpl1 transcript. The first two AUG codons from which translation of VP1 begins are indicated in green bold.

Figure S2. Mass-spectrometric identification (peptide mass fingerprinting) of BgDNV VP2, represented by an ~85 kDa protein band. (A) MALDI-TOF spectrum of the corresponding trypsin-digested band. (B) List of mass/charge (m/z) values for peptide ions detected in the course of mass-spectrometric analysis. (C) The obtained m/z values were analyzed using Mascot search software ( and peptide matches to the virus ORF are indicated in the amino acid sequence with red color. The first two AUG codons from which translation of VP2 begins are indicated in green bold.

Figure S3. Mass-spectrometric identification (peptide mass fingerprinting) of BgDNV VP2, represented by an ~80 kDa protein band. (A) MALDI-TOF spectrum of the corresponding trypsin-digested band. (B) List of mass/charge (m/z) values for peptide ions detected in the course of mass-spectrometric analysis. (C) The obtained m/z values were analyzed using Mascot search software ( and peptide matches to the virus ORF are indicated in the amino acid sequence with red color. The first two AUG codons from which translation of VP2 begins are indicated in green bold.

Figure S4. Mass-spectrometric identification (peptide mass fingerprinting) of BgDNV VP3. (A) MALDI-TOF spectrum of the corresponding trypsin-digested band. (B) List of mass/charge (m/z) values for peptide ions detected in the course of mass-spectrometric analysis. (C) The obtained m/z values were analyzed using Mascot search software ( and peptide matches to the respective virus ORF are indicated in the amino acid sequence with red color. The first two AUG codons from which translation of VP2 begins are indicated in green bold.

Figure S5. Mass-spectrometric identification (peptide mass fingerprinting) of bands p40, p36, and p27 presumably corresponding to the products of BgDNV capsid protein proteolytic cleavage. Peptide matches to viral ORF1 are indicated in the amino acid sequence with red color in each case.
