Sequence Comparison of PMEIs form Kiwi (AcPMEI), PMEIs from Arabidopsis (AthPMEI-1, Accession Number NP_175236; AthPMEI-2, Accession Number NP_188348), and Invertase Inhibitor from Tobacco (NtCIF).
Residues of the kiwi inhibitor involved in H-bonds (violet), Van der Waals contacts (green), and water-mediated H-bonds (yellow) with tomato PME are shown. Conserved residues are in blue.
