Figure 1.

Multiple sequence alignment of all myticalin precursor sequences identified in Mytilus spp. Signal peptide, mature peptide region, dibasic propeptide cleavage site and anionic C-terminal extension regions are highlighted. Amino acids are colored according to their chemical-physical properties. All the reported sequences pertain to the Mytilus edulis species complex (M. galloprovincialis, M. edulis, M. trossolus and M. chilensis), with the exception of myticalin A1, A2, A6, A7, C4 and C7, which were identified in M. californianus.
