Structure-Based Sequence Alignment of the Reported PAL from Parsley (Top Line) with HAL from Pseudomonas putida.

Every tenth residue is marked by a dot or comma wherever possible. The secondary structure is from PAL. Lower-case letters indicate lack of structure. The underlined residues align within a 3-Å distance cutoff for Cα atoms. The asterisks denote 97 strictly conserved positions within the PAL family (above the line) and 65 within the HAL family (below). Thr549 corresponding to the phosphorylated Thr of the PAL from French beans (Allwood et al., 1999) is black/white inverted. The alignment results in 144 identical residues (not marked).
