Site-directed mutagenesis of the phosphate-binding consensus sequence in Escherichia coli adenylosuccinate synthetase.

The Journal of biological chemistry - 5 Feb 1992

Liu F, Dong Q, Fromm H J

Abstract excerpt

Adenylosuccinate synthetases from different sources contain an N-terminal glycine-rich sequence GDEGKGK, which is homologous to the conserved sequence GXXXXGK found in many other guanine nucleotide-binding proteins or enzymes. To determine the role of this sequence in the structure and function of Escherichia coli adenylosuccinate synthetase, site-directed mutagenesis was performed to generate five mutant...
