Molecular Recognition and Immunopharmacological Implications of Serratiopeptidase Targeting Snake Venom Bradykinin-Potentiating Peptides

  Molecular Recognition and Immunopharmacological Implications of Serratiopeptidase Targeting Snake Venom Bradykinin-Potentiating Peptides Abstract Purpose Bradykinin-potentiating peptides (BPPs), found in snake venom, are known to modulate cardiovascular functions, but their susceptibility to enzymatic degradation remains poorly understood. Methods Models were generated using AlphaFold-Colab for five small BPPs (< 9 amino acids) that did not have experimentally solved structures, and those BPPs which had reliable predictions of structure (pLDDT > 80) were used for docking studies. Protein-peptide docking experiments were done using HADDOCK for studying the interaction between wild-type (WT) and mutant serratiopeptidase with BPPs. After selecting the best complex, simulation of the complex was done using molecular dynamics (MD) simulations for 100 ns and binding energy determination using MM/PBSA analysis. For checking the mechanical stability of the protein-peptide complexes...

Three new species of orb-weaver spiders (Araneidae) from Humid Chaco in south-west Paraguay

Abstract 


Three new species of orb-weaver spider are described from Paraguay. Kaira mbywangiae sp. nov. has a remarkable complexity of abdominal humps and hump regions. Two species are described from the Humid Chaco flooded wetland region of Ñeembucú (Eustala davalosae sp. nov. and Kaira mbywangiae sp. nov.), and one from an Atlantic rainforest fragment in eastern Itapuá (Mangora sandovalae sp. nov.).
