Abstract |
Sarcotoxin IA is a cecropin-type antibacterial peptide of flesh fly. Using a mutant sarcotoxin IA lacking two N-terminal residues, we demonstrated that these residues are indispensable for its antibacterial activity against Escherichia coli and LPS-binding. Contrary to the native sarcotoxin IA, the mutant sarcotoxin IA could not neutralize various biological activities of LPS. It was suggested that sarcotoxin IA firmly binds to the lipid A core of LPS via these two N-terminal residues and forms a stable binding complex that exhibits no appreciable biological activity like native LPS. |
