Amino acid sequence alignment of γ-TMT proteins. Comparison of the deduced amino acid sequences of γ-TMT1, γ-TMT2, and γ-TMT3 with those of other plants green algae and cyanobacterium. For B. napus (EU637012.1) and H. annuus (DQ229832.1), only one of the sequences was used for alignment. The sequences were compared with A. thaliana γ-TMT (VTE4) as a standard; identical residues in other sequences are shaded, and gaps introduced for alignment purposes are indicated by dashes (-). Lines under amino acid sequences represented plastid transit peptides, which were predicted by using ChloroP1.1 [37]. Blocks surrounded by black boxes are conserved SAM-binding domains, as reported by Shintani and DellaPenna [21].
