Spontaneous chemical reversion of an active site mutation: deamidation of an asparagine residue replacing the catalytic aspartic acid of glutamate dehydrogenase.
A mutant (D165N) of clostridial glutamate dehydrogenase (GDH) in which the catalytic Asp is replaced by Asn surprisingly showed a residual 2% of wild-type activity when purified after expression in Escherichia coli at 37 degrees C. This low-level activity also displayed Michaelis constants for subst...
