Research Abstract |
Our results revealed that the synthetic peptide corresponding to partial amino acid sequence (KVFLECCNLMKTHKNMKTE) of C3a region of carp C3 isotype (C3-Q1) was antibacterial, and acted on Gram-negative bacteria, Escherichia coli. (XL1-Blue mrf and O157:H7 (VT1 and VT2)) and S.Enteritidis. We successfully enhanced antibacterial activity, by partially replacing amino acids of above-mentioned sequence. However, it was found that enhancement of antibacterial activity led to high cytotoxic activity. Hereafter, we aim to create antimicrobial peptides with low side effects on the basis of observation in this study.
