Antibacterial Activity and Toxicity of Analogs of Scorpion Venom IsCT Peptides [PDF]

Antibiotics, 2017
Seven analogs of the natural, α-helix peptides IsCT1 and IsCT2—found in the venom of scorpion Opithancatus Madagascariensis—have been synthesized and tested to compare their antibacterial and hemolytic activity against natural peptides. In general, results show that increasing hydrophobicity by substituting positions 5 and 9 of the sequences with ...

BmK-YA, an Enkephalin-Like Peptide in Scorpion Venom

PLoS ONE, 2012
By screening extracts of venom from the Asian scorpion Buthus martensii Karsch (BmK) for their abilities to activate opioid receptors, we have identified BmK-YA, an amidated peptide containing an enkephalin-like sequence. BmK-YA is encoded by a precursor that displays a signal sequence and contains four copies of BmK-YA sequences and four of His(4)-BmK-
