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...

A new trapdoor spider, Nemesia hesperides sp. nov. (Araneae: Mygalomorphae: Nemesiidae), from a home garden

ABSTRACT


Home gardens can serve as refuges for arthropod biodiversity. Here we describe a new species of trapdoor spider known only from a home garden. Nemesia hesperides sp. nov. builds a simple burrow with a wafer-type trapdoor formed by a fine sheet of web, characteristic shared with N. dorthesi Thorell, 1875, N. entinae Calvo & Pagán, 2022, N. santeugenia Decae, 2005, N. santeulalia Decae, 2005 and N. shenlongi Pertegal et al., 2022, species that share a similar morphology. The presence of Nemesia hesperides sp. nov. in a garden managed by ecological methods and its absence in the surrounding gardens managed only for a recreative use, shows the importance that management plays in the conservation role of home gardens.
