Protein
Css54
Gene
N/A
Organism
Centruroides suffusus (Durango bark scorpion)
Status
Functioni
Amphipathic peptide that shows antibacterial activity against E.coli (MIC=12.5 µg/ml) and S.aureus (MIC=12.5 µg/ml). Increases efficacy of antibiotics (ethambutol, pyrazinamide, isoniazid, rifampicin) when tested against S.aureus, probably by facilitating their incorporation into the bacteria. Has hemolytic activity against human erythrocytes (25 µM provokes 83% of hemolysis).
