Protein

Inorganic pyrophosphatase, mitochondrial

Gene

PPA2

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Involved in energy production. Its activity is stimulated by uncouplers of ATP synthesis.

Catalytic activityi

Diphosphate + H2O = 2 phosphate.

Cofactori

Mg2+By similarityNote: Binds 4 Mg2+ ions per subunit. Other metal ions can support activity, but at a lower rate. Two Mg2+ ions are required for the activation of the enzyme and are present before substrate binds, two additional Mg2+ ions form complexes with substrate and product.By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
