a Peptide mass fingerprint (based on positive ion MALDI reflectron MS) of NP forms (depicted in Fig. 1, reduced sample). Green (bottom) mass spectrum – NP apparent molecular mass 48 kDa; blue (middle) mass spectrum – NP apparent molecular mass 55 kDa; red (top) mass spectrum – NP apparent molecular mass 61 kDa. (full list of peptides with matching theoretical peptides is given in Additional file 1: Table S1). b Sequence coverage of NP bands from Fig. 1. Red line – NP apparent molecular mass 61 kDa; blue line – NP apparent molecular mass 55 kDa; green line – NP apparent molecular mass 48 kDa. Possibly modified amino acids are underlined
