Anti-Gram+ & Gram-, Antiviral, Antifungal, Antiparasitic, Spermicidal, Anti-HIV, Antimalarial, Hemolytic,

 
 

Additional info:

Active against S. aureus (MIC 13-29ug/ml), C. albicans (MIC 11.5-26ug/ml) and N. gonorrheae (MIC 51-103ug/ml). It also showed activities against P. falciparum (antimalarial) as well as human sperm. Based on the primary structure, it can be fitted to a class L amphipathic alpha helix which places all K on the polar face. The N-terminal region is responsible for both oligomerization and hemolytic activity. NMR structures of two derivatives have been solved [2DD6 for K4-S4(1-13) and 2DCX for NC12-K4S4(1-13)]. The 3D structures remain the same. You can rotate, zoom, and view the 2DD6 structure here in the PDB. Sequence has been corrected based on the original paper. 3/2015 GW; 4/2019 C Wang.
