Molecular Cloning and Characterization of a Soluble Inorganic Pyrophosphatase in Potato. [PDF]
A cDNA clone encoding a soluble inorganic pyrophosphatase (EC 3.6.1.1) of potato (Solanum tuberosum L.) was isolated by screening a developing tuber library with a heterologous probe. The central domain of the encoded polypeptide is nearly identical at the sequence level with its Arabidopsis homolog (J.J. Kieber and E.R. Signer [1991] Plant Mol Biol 16:

Structure of the Mycobacterium tuberculosis Soluble Inorganic Pyrophosphatase Rv3628 at pH 7.0 [PDF]
The 1.5 Å resolution crystal structure of the Mycobacterium tuberculosis soluble inorganic pyrophosphatase Rv3628 at pH 7.0 is reported. The M. tuberculosis and M. leprae genomes include genes for the only two family I inorganic pyrophosphatases known to contain two histidines in the active site. The role of these two residues in catalysis is not fully

Bacillus subtilis ORF yybQ Encodes a Manganese-Dependent Inorganic Pyrophosphatase With Distinctive Properties: The First of a New Class of Soluble Pyrophosphatase? [PDF]
The N-terminal 15 amino acids of the major protein associated with inorganic pyrophosphatase activity in Bacillus subtilis WB600 are identical to those of B. subtilis ORF yybQ. This ORF was amplified from B. subtilis WB600 DNA by PCR and cloned into an overexpression vector in Escherichia coli.

Evolutionary Conservation of the Active Site of Soluble Inorganic Pyrophosphatase
Soluble inorganic pyrophosphatases (PPases) are essential enzymes that are important for controlling the cellular levels of inorganic pyrophosphate (PPi). Although prokaryotic and eukaryotic PPases differ substantially in amino acid sequence, recent evidence now demonstrates clearly that PPases throughout evolution show a remarkable level of ...

We have solved the structure of two active-site variants of soluble inorganic pyrophosphatases (PPase), R78K and D117K, at resolutions of 1.85 and 2.15 A and R-factors of 19.5% and 18.3%, respectively. In the R78K variant structure, the high-affinity phosphate group (P1) is missing, consistent with the wild-type structure showing a bidentate ...

PPA1, an energy metabolism initiator, plays an important role in the progression of malignant tumors
Inorganic pyrophosphatase (PPA1) encoded by PPA1 gene belongs to Soluble Pyrophosphatases (PPase) family and is expressed widely in various tissues of Homo sapiens, as well as significantly in a variety of malignancies.

Excess PPi triggers developmental defects in a cell-autonomous manner. The level of inorganic pyrophosphate (PPi) must be tightly regulated in all kingdoms for the proper execution of cellular functions. In plants, the vacuolar proton pyrophosphatase (H+-

The structure of E.coli soluble inorganic pyrophosphatase at 2.7 Å resolution [PDF]
The structure of E.coli soluble inorganic pyrophosphatase has been refined at 2.7 A resolution to an R-factor of 20.9%. The overall fold of the molecule is essentially the same as yeast pyrophosphatase, except that yeast pyrophosphatase is longer at both the N- and C-termini.
