The three-dimensional structures of four mutant E. coli inorganic pyrophosphatases (PPases) with single Asp-->Asn substitutions at positions 42, 65, 70, and 97 were solved at 1.95, 2.15, 2.10, and 2.20 A resolution, respectively. Asp-42-->Asn and Asp-65-->Asn mutant PPases were prepared as complexes with sulfate--a structural analog of phosphate, the product of enzymatic reaction ...
