Myticin is a cysteine-rich peptide produced in three isoforms A B and C by Mytilus galloprovincialis (Mediterranean mussel). Isoforms A and B show antibacterial activity against Gram-positive bacteria while isoform C is additionally active against the fungus Fusarium oxysporum and bacterium Escherichia coli (streptomycin resistant strain D31). Myticin-prepro is the precursor peptide.
