Alignment of deduced amino acid sequences of Arabidopsis (At) and lettuce (Ls) lycopene ɛ-cyclases. Residues identical for both sequences in a given position are in white text on a black background. A region of interest is underlined. The alignment was created by using clustal x Ver. 1.8 (17). GenBank accession nos. are listed at the ends of the sequences. Asterisks above the alignment are spaced every 10 residues. Numbers to the right denote the number of the amino acid residue that ends the row.
