The enzyme [pyruvate dehydrogenase (acetyl-transferring)]-phosphatase (EC 3.1.3.43) catalyzes the reaction
- [pyruvate dehydrogenase (acetyl-transferring)] phosphate + H2O [math]\displaystyle{ \rightleftharpoons }[/math] [pyruvate dehydrogenase (acetyl-transferring)] + phosphate
This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name is [pyruvate dehydrogenase (acetyl-transferring)]-phosphate phosphohydrolase. Other names in common use include pyruvate dehydrogenase phosphatase, phosphopyruvate dehydrogenase phosphatase, [pyruvate dehydrogenase (lipoamide)]-phosphatase, and [pyruvate dehydrogenase (lipoamide)]-phosphate phosphohydrolase.
Structural studies
As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 2PNQ.
