(a) Alignment and distribution of key amino acids residues for CAT proteins. The transition between residues C and T is marked above the sequence alignment. The distribution of T/C residues from distinct species is displayed in the right side. (b) Homolog models of At_CAT1, At_CAT2 and At_CAT3. Dashed yellow lines represent hydrogen bonds
