Prediction of NnPAL1 secondary structure and tertiary structure. (A) Prediction of the NnPAL1 secondary structure. The blue, pink, red, and green regions represent the alpha helix, random coil, extended strand, and beta turn, respectively. (B) The three domains of the predicted tertiary structure of NnPAL1 established by homology-based modelling (9 strictly conserved residues are marked).
