Peptide sequence comparison of PP2C genes. Multiple sequence alignment of PP2C5 to Medicago sativa MSMP2C (Y11607) and A. thaliana PP2C proteins; ABI1 (GenBank accession no. X77116), ABI2 (Y08965), AtP2C-HA (ATAJ3119), and ATHPP2Ca (D38109). Note the high level of conservation at the putative phosphate-binding site (○), putative metal binding sites (●) and the position of the ABI1 and ABI2 mutation (■). Sites were determined from homology to previously characterized PP2C proteins (Leung et al. 1994, 1997; Meyer et al. 1994; Das et al. 1996). Shading, on the basis of the PP2C5 sequence, shows conserved residues with a black background and similar residues with a gray background.
