An homology model of human adenylosuccinate lyase structure shows that P100A substitution distorts the amino acid chain of domain I in the proximity of His-86, which behaves as general acid in the catalysis, and may expose Cys-98 and Cys-99 to oxidising agents. This model is in line with the observation that the defective protein is strongly inhibited by 4-hydroxy-2-nonenal, an hydroxyalkenal that is known to form thio-ether linkage with proteins.
