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...

Description of a new Psalmopoeus Pocock, 1895 species (Araneae, Theraphosidae, Psalmopoeinae) from the Chocó region of Ecuador

Abstract

A new species of Theraphosidae, genus Psalmopoeus Pocock, 1895 is described from the Chocó region of Ecuador, Psalmopoeus pristirana n. sp. (male and female). The identity of the female of the recently described Psalmopoeus satanas Peñaherrera-R. & León-E., 2023 is discussed. Images of Psalmopoeus ecclesiasticus Pocock, 1903 are given for comparison and a distribution map of all Ecuadorian Psalmopoeus species is presented.
