Schematic representation of the predicted domain structure of Arabidopsis PAEs. a PAEs with signal peptide (SP). b PAEs without SP. All the Arabidopsis PAE proteins display the Pfam domain (PF 032283), characteristic of PAE protein of the CE13 family. The characteristics of these domains are summarized in Additional file 3. c Plant PAE conserved motifs. d Arabidopsis PAE consensus sequences. The conserved amino acid residues are in red and the similar residues are in black. The catalytic triad, S, D, H, is in orange. Cysteine residues are in olive
