Abstract
Peptides derived from shrimp hemocyanin have antimicrobial properties This is the first report of hemocyanin cDNA FCHc cloned from Fenneropenaeus chinensis and recombinant expression of two Cterminal fragments Based on sequence analysis of Fenneropenaeus chinensis hemocyanin FCHc we subcloned two FCHc fragments by designing special primers Two antimicrobial peptides AMPs were derived from FCHc FCHcC1 and FCHcC2 The recombinant sequence of FCHcC1 consisted of 207 bp encoding 69 amino acids and the recombinant sequence of FCHcC2 consisted of 120 bp encoding 40 amino acids The results of Tricine–sodium dodecyl sulfatepolyacrylamide gel electrophoresis and Western blotting indicated that recombinant FCHcC1 and FCHcC2 peptides rFCHcC1 and rFCHcC2 were expressed successfully An inhibition assay showed that FCHcC1 and FCHcC2 were anionic AMPs with antifungal and antibacterial activities
