Table 3. P. insidiosum’s transcriptome-derived Exo1 homologous proteins that share the Peptide-A, -B, or -C sequences.

Predicted structures of these proteins are shown in Fig 2. NCBI accession number, protein length, calculated protein molecular weight (MW), number of 454-derived transcript reads (when P. insidiosum grew at 37°C), and sequence alignment analysis against Exo1 (including: query sequence coverage, E-value, and sequence identity), corresponding to each transcriptome-derived protein, are summarized in the table.
