| Outline of Final Research Achievements |
We estimated the venom composition of predatory ant species, Odontomachus monticola and Pachycondyla chinensis, by combined transcriptome and peptidome analysis. We found novel bioactive peptides in Odontomachus monticola, which we termed pilosulin-like peptides 1, 2, 3, 4, 5, and 6 by transcriptome analysis. They were major components of the venom of Odontomachus monticola. As minor components, we found ICK-like peptides, enzymes, enzyme inhibitors and so on. Pilosulin-like peptides displayed antibacterial, histamine releasing, and hemolytic activities. And some of the ICK-like peptides inhibited Drosophila sodium channel activity.
