1.C.81.1.1
Arenicin-1 precursor (202 aas). The processed pore-forming β-hairpin antimicrobial peptide corresponds to residues 182-202 (Andrä et al., 2008; Shenkarev et al., 2011). Low-conductivity pores were detected in the phosphatidylethanolamine-containing lipids and high-conductivity pores in anionic lipids. The measured conductivity levels agreed with the model in which arenicin antimicrobial activity was mediated by the formation of toroidal pores assembled of two, three, or four β-structural peptide dimers and lipid molecules (Shenkarev et al., 2011).
