An antibacterial peptide from skin extract of the catfish Silurus asotus was purified and characterized. The acidified skin extract was put through a Sep-Pak C18 solid phase extraction cartridge using a stepwise gradient and divided into flow-through (F.T.), 10% methanol-elute (RM10), 60% methanolelute (RM60), and 100% methanol-elute (RM100) fractions. RM10, RM60, and RM 100 showed antimicrobial activity against Escherichia coli D31. On the other hand, the F.T. fraction did not show antimicrobial activity. Among the various fractions, RM 60 had the highest activity. RM 60 was partially purified on a cation exchange column (CM52) by a stepwise gradient. The ammonium acetate (pH 5.15) 0.02 M – 0.8 M fraction showed antimicrobial activity. Then an antimicrobial peptide was purified using a 0.6M fraction with strong antibacterial activity through a series of five C18 reversed-phase HPLC columns. For the characterization of the purified peptide, the molecular weight and amino acid sequence were analyzed by MALDI-TOF MS and Edman degradation. The molecular weight of this peptide was about 4182.1 [M+H]+. The amino acid sequence of this peptide was partially determined as follows: PALXXKARREAKVKF. These findings suggest that this peptide plays a significant role in the innate defense system of catfish skin.
