UniProtKB - P0C8W1 (NDB4S_HOFGE)
Non-disulfide-bridged peptide 5.5
Functioni
Antimicrobial peptide (PubMed:28275372).
Is active on Mycobacterium abscessus subsp. massiliense (MBC=200 µM), a rapidly growing and emerging pathogen associated with healthcare infections (PubMed:28275372).
Also show antifungal activities (By similarity).
Has a weak hemolytic activity on human erythrocytes (10% at 610 µM), indicating a low toxicity (therapeutic index (TI)=3.05) (PubMed:28275372).
In addition, treatment of infected macrophages reduces the bacterial load (PubMed:28275372).
In vivo, treatment of M.abscessus-infected mice causes a decrease in the bacterial load in the lungs and liver (PubMed:28275372).
