General Information

General Information Comment Organism
physiological function mechanism of Sap-mediated import of antimicrobial peptides, a strategy to reduce periplasmic and inner membrane accumulation of these host defense peptides. Antimicrobial peptides localize to the bacterial cytoplasm of the wild-type strain and are susceptible to cytoplasmic peptidase activity. In bacteria lacking a functional Sap permease complex, antimicrobial peptides accumulate in the periplasm. The periplasmic binding protein SapA binds antimicrobial peptides and is required for virulence in vivo Haemophilus influenzae
