The three-dimensional structure of inorganic pyrophosphatase from Escherichia coli complexed with sulfate was determined at 2.2 A resolution using Patterson's search technique and refmed to an R-factor of 19.2%. Sulfate may be regarded as a structura

Escherichia coli inorganic pyrophosphatase (PPase) is a hexamer of identical subunits. This work shows that trimeric form of PPase exhibits the interaction of the active sites in catalysis. Some trimer subunits demonstrate high substrate binding affi

Magnesium-supported PPi hydrolysis by the mutant Asp-67Asn E. coli pyrophosphatase at saturating PPi and metal-activator concentrations in the presence of NaF is followed by a gradual decrease in the initial rate of PPi hydrolysis. The reaction occur

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-6

The three-dimensional structures of E. coli inorganic pyrophosphatase (PPase) and its complexes with Mn2+ in a high affinity site and with Mg2+ in high and low affinity sites determined by authors in 1994-1996 at 1.9-2.2 A resolution are compared. Me

The hexameric inorganic pyrophosphatase (PPase) is irreversibly inactivated by phosphoric acid monoesters. The inactivation kinetics are consistent with the formation of a dissociable complex of the phosphoric acid monoester with the enzyme, followed

By the peptide map method, a phosphorylated peptide has been isolated from a tryptic hydrolysate of phosphorylated yeast inorganic pyrophosphatase (I), and this is a direct proof of the formation of a covalent bond between (I) and phosphate in the co

Inorganic pyrophosphatases of baker's yeast and E. coli are oligomers built of chemically identical subunits. Both enzymes are active in the monomeric state. Each subunit has an active and an allosteric site linked by hetero- and homotropic interacti

Baker’s yeast pyrophosphatase (EC 3.6.1.1) displays half-of-the-sites reactivity with respect to the inhibitors, phosphoric acid monoesters [ 1,2]. The enzyme catalyzes the hydrolysis and synthesis of inorganic pyrophosphate. It is a dimeric protei
