21. It is also 29 % identical to the amino acid residues of the frog antimicrobial peptide dermaseptin. 22. A major challenge associated with systemic delivery of an antimicrobial peptides is their susceptibility to proteolytic degradation. 23. Generally, in any sample collected there are multiple antimicrobial peptides released, each serving a different specific function. 24. Lipid II interacts with human alpha defensins, a class of antimicrobial peptides , such as Defensin, alpha 1. 25. "Antimicrobial peptides " are an evolutionarily immunity. 26. They may also occur in BcL-2 like protein, in some amphiphilic antimicrobial peptides , and in certain annexins. 27. Cathelicidin is cleaved into the antimicrobial peptide LL-37 by both kallikrein 5 and kallikrein 7 serine proteases. 28. Another research team was able to use bacteriocins, antimicrobial peptides and bacteriophages in the control of bacterial infections. 29. A number of antimicrobial peptides have also been found in the venom of " M . eupeus ". 30. The first 20 amino acids are a putative signal peptide, and the antimicrobial peptide expressed mainly in the haemocytes.
