abstract：:Magainins are a family of antimicrobial peptides present in the skin extracts of Xenopus laevis. Both magainin-1 and -2 do not have any significant effect on the activity of protein kinase C (PKC). Magainin-2 was found to be readily phosphorylated by PKC to 0.5 mol 32P/mol of peptide. Neither magainin-1, which has a s...
