Peptides identified in the venom proteome of Physocyclus mexicanus summarized by homologous groups (families). The pie chart on the left indicates the proportions of non-redundant polypeptide sequences detected in the proteome for each group, and represents the sequence diversity within and among the peptide families. The pie chart on the right indicates the proportion of peptide families as measured by abundance of unique tryptic peptides in the proteome. The table details the number of non-redundant sequences (#nr seqs), the number of unique tryptic peptides, the number of cysteines in the mature peptide, whether or not the peptides are predicted to have an ICK fold, and the estimated molecular weight of the mature peptide.
