(pyruvate dehydrogenase (acetyl-transferring))-phosphatase

In enzymology, a [pyruvate dehydrogenase (acetyl-transferring)]-phosphatase () is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are pyruvate dehydrogenase (acetyl-transferring) phosphate and HO, whereas its two products are pyruvate dehydrogenase (acetyl-transferring) and phosphate.
This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name of this enzyme class 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.
