Comparative proteomes and peptides of mucus from seven gastropod species. (A) Number of protein bands of the mucus proteins from seven gastropod species separated by 1D-SDS-PAGE and stained by Coomassie brilliant blue (blue) and silver nitrate (red) as counted by the GelAnalyzer program. The number of protein bands is shown on the x-axis. The gastropod species are shown on the y-axis. (B) Functional annotation terms of the mucus proteome in three Gene Ontology categories (y-axis) biological process (BP), molecular function (MF), and cellular component (CC). The x-axis represents the number of proteins. (C) The number of different peptides identified in the mucus of seven gastropod species. These peptide data were obtained from the mass spectrometric analysis. The number of peptides is shown on the x-axis. AF = Achatina fulica; PC = Pomacea canaliculata; CS = Cryptozona siamensis; SS = Semperula siamensis; HD = Hemiplecta distincta; CF = Cyclophorus fulguratus; and HP = Helix pomatia.
