Scorpion venom as antimicrobial peptides (AMPs): A review article

Abstract: The high level of reported multidrug resistant pathogens with the failure of most conventional antibiotic to kill many of them arise the global concern in the last decade to find alternatives urgently. Many researches have been conducted on scorpion venom biological characteristics, and its different antimicrobial peptides had been reported in literature since the last decade. Here short overview of all scorpion AMPs with antibacterial activity, their structural determinants, classification types and their mod… Show more

“…Like many other antimicrobial peptides, meucins are believed to represent ancient biological weapons against bacteria that selectively target the bacterial cell surface [140]. The selectivity is mainly based on their cationic charge which attracts them to negatively charged groups in bacterial plasma membranes [141]. Their amphipathic nature and relatively low molecular mass (< 10 kDa) allows them to accumulate in the membranes where they form transient pores, perturb membrane integrity, and cause cell lysis [141].…”

Their amphipathic nature and relatively low molecular mass (< 10 kDa) allows them to accumulate in the membranes where they form transient pores, perturb membrane integrity, and cause cell lysis [141]. Notably, the specificity of antimicrobial peptides to microbes is based on the uniquely anionic charge on bacterial plasma membranes conferring a negative charge on their surface, a feature that distinguishes (the prokaryotic) bacteria from eukaryotes whose cell surfaces are largely neutral [142,143].…”

“…Após o PAM se fi xar na membrana iniciase a desestabilização da parede microbiana por meio da formação de poros ou a atividade de enfraquecimento da membrana. As formas de atuação dos peptídeos na membrana bacteriana foi estudada ao longo do tempo e elucidadas várias maneiras de interação, como demonstra a Figura 2(CALISKAN et al, 2013a;TARAZI, 2015). pela membrana bacteriana direcionando fosfolipídios oxidados; peptídeos podem induzir pequenos ânions por meio da bicamada, resultando no efl uxo, o potencial de membrana pode ser dissipado sem outro dano aparente, ou, também podemos observar inversamente, no modelo molecular de eletroporação, a acumulação de peptídeo na monocamada externa que aumenta o potencial da membrana a um limiar que torna a membrana porosa a transitoriedade de várias moléculas, incluindo o peptídeo que causou este efeito(NGUYEN, et al, 2011) (ADAPTADO).…”
