1.C.124.1.1









Pandinin2 of 24 aas and 1 TMS.  Forms pores and disrupts membranes of bacteria and fungi (Rodríguez et al. 2014).

Eukaryota
Metazoa, Arthropoda
Pandinin-2 of Pandinus imperator
1.C.124.1.2









Heterin-1 of 43 aas and 1 TMS.  Heterin-1 possesses potent activities against both Gram-positive and Gram-negative bacteria. Among the tested bacterial species, Heterin-1 is the most active against Bacillus megaterium and Micrococcus luteus with MICs of 4.0 μM for both (Wu et al. 2014).

OcyC3 of Opisthacanthus cayaporum (South American scorpion)
1.C.124.1.5









Ponericin-W5 of 24 aas and 1 TMS. Has a broad spectrum of activities against both Gram-positive and Gram-negative bacteria as well as Saccharomyces cerevisiae. It also has insecticidal and hemolytic activities (Orivel et al. 2001).

Ponericin-W5 of Pachycondyla goeldii (Ponerine ant)
1.C.124.1.6









Antimicrobial peptide, AMP, of 76 aas and 1 N-terminal TMS.  It is similar to a characterized AMP that forms toroidal pores, reported by Bertelsen et al. 2023.

Metazoa, Arthropoda
AMP of Pandinus cavimanus (Tanzanian red clawed scorpion)
1.C.124.2.1









Pandinin 1, Pin1, of 44 aas and 0 TMSs.  Pin1 is located at the membrane-water interface, approximately parallel to the bilayer surface. Solid-state NMR results correlated well with the observed biological activity of pin1 in red blood cells and bacteria (Nomura et al. 2005). Pin-1 and Pin-2 are not demonstrably homologous. However, Pin1 shows 30% identity with a central part of 1.C.17.2.2.
