2. Supplementary Fig. 2 The deduced amino acid sequence alignments of four groups of genes with same mature proteins. The three, two and two sequences with the same N-terminal METSCIP- are shown in a, b and c, respectively. The two sequences with the same N-terminal METSRVP- are shown in d. Short bars indicate the nucleotide sequences were the same among (between) the sequences compared, * indicates stop codons Ta-17
