Fig. 2.

Alignments of M-ORF protein sequences. Global alignments and alignments for each subfamily are shown. a All M-ORF sequences, b M-ORFs from the subfamily Unioninae, c M-ORFs from the subfamily Gonideinae, d M-ORFs from the subfamily Ambleminae. Colour coding is applied to amino acid groups conserved in ≥70 % of sequences. Grey, aliphatic amino acids; orange, aromatic amino acids; yellow, sulfur amino acids; green, amino acids bearing a hydroxyl group; red, basic amino acids; blue, acidic amino acids; brown, amino acids with an amide group; pink, cyclic amino acids
