Chemical and Biological Characteristics of Antimicrobial alpha-Helical Peptides Found in Solitary Wasp Venoms and Their Interactions with Model Membranes
(Mdpi, 2019-10-01)
Solitary wasps use their stinging venoms for paralyzing insect or spider prey and feeding them to their larvae. We have surveyed bioactive substances in solitary wasp venoms, and found antimicrobial peptides together with ...
Interaction of cyclic and linear labaditin peptides with anionic and zwitterionic micelles
(2014)
Conformational changes of the cyclic (Lo) peptide Labaditin (VWTVWGTIAG) and its linear analogue (L1) promoted by presence of anionic sodium dodecyl sulfate (SDS) and zwitterionic L-α-Lysophosphatidylcholine (LPC) micelles ...
Eumenitin, a novel antimicrobial peptide from the venom of the solitary eumenine wasp Eumenes rubronotatus
(Elsevier B.V., 2006-11-01)
A novel antimicrobial peptide, eumenitin, was isolated from the venom of the solitary eumenine wasp Eumenes rubronotatus. The sequence of eumenitin, Leu-Asn-Leu-Lys-Gly-Ile-Phe-Lys-Lys-Val-Ala-Ser-Leu-Leu-Thr, was mostly ...

Linear peptide analogues from Jatropha's orbitides promote migration of human neonatal foreskin fibroblasts in vitro and collagen deposition
(2019-01-01)
Orbitides are a class of small naturally occurring cyclic peptides with structural and functional diversities. Their chemical properties make this class feasible to be obtained by solid phase peptide synthesis (SPPS). ...
Cyclic, Linear, Cycloretro-Isomer, and Cycloretro-Inverso Peptides Derived from the C-Terminal Sequence of Bradykinin as Substrates or Inhibitors of Serine and Cysteine Proteases
(Springer, 2004-05-01)
We investigated the inhibition of trypsin, human tissue (hK1) and human plasma kallikrein (HuPK), papain, and cathepsin L, B, and X by synthetic cyclic, cycloretro-isomer, cycloretro-inverso, and linear peptides derived ...
Cationic antimicrobial peptides inactivate shiga toxin-encoding bacteriophages
(Frontiers Media S.A., 2018)
Shiga toxin (Stx) is the principal virulence factor during Shiga toxin-producing Escherichia coli (STEC) infections. We have previously reported the inactivation of bacteriophage encoding Stx after treatment with chitosan, ...
Chemometric analysis of Hymenoptera toxins and defensins: A model for predicting the biological activity of novel peptides from venoms and hemolymph
(2011-09-01)
When searching for prospective novel peptides, it is difficult to determine the biological activity of a peptide based only on its sequence. The trial and error approach is generally laborious, expensive and time consuming ...
