A new T677C mutation of the aspartoacylase gene encodes for a protein with no enzymatic activity.

[canavan disease]

To verify the effect of and to date the unknown T677C mutation of the human N-acetylaspartoacylase (hASPA) gene on the function of the mutated enzyme.Wild type and I226T-mutated proteins were expressed and purified from a transformed Escherichia coli colony. Enzymatic activities were measured in the presence of varying substrate concentrations.Whilst kinetic parameters of wild type hASPA were in line with data in literature, I226T-mutated hASPA showed no enzymatic activity.Data indicated that this new mutation might be responsible in homozygosis for the phenotype corresponding to Canavan disease.
