產(chǎn)品介紹 |
background: No data available. Function: Cecropins have lytic and antibacterial activity against several Gram-positive and Gram-negative bacteria. Subcellular Location: Secreted. Post-translational modifications: A protein with the same sequence as cecropin A, but lacking the carboxyl blocking group, has been isolated and called cecropin C (PubMed:7140755). Similarity: Belongs to the cecropin family.
