Structure:

Additional info:

Rich in P and R. Bac7(1-35) has antibacterial activity similar to bac7. Mechanism of action: At ~MIC, the fragment binds to internal targets via stereospecific uptake (because all-D-enantiomer failed to be taken in and much less active); at higher concentrations, it works via non-specific membranolytic mechanism. Bac(1-16) is still active against E. coli and S. enterica but kinetically deficient compared to bac(1-35). Bac(5-35) is much less active, indicating the importance of the N-terminal segment (Biochim Biophys Acta 2006; 1760: 1732-1740). Updated 10/15/2008.
