What is "phosphoenolpyruvate mutase"

n. (context biochemistry English) A phosphotransferase enzyme that catalyzes the chemical reaction ''phosphoenolpyruvate $rightleftharpoons$ 3-phosphonopyruvate''.

In enzymology, a phosphoenolpyruvate mutase is an enzyme that catalyzes the chemical reaction

phosphoenolpyruvate $\rightleftharpoons$ 3-phosphonopyruvate

Hence, this enzyme has one substrate, phosphoenolpyruvate (PEP), and one product, 3-phosphonopyruvate (PPR), which are structural isomers.

This enzyme belongs to the family of isomerases, specifically the phosphotransferases (phosphomutases), which transfer phosphate groups within a molecule. The systematic name of this enzyme class is phosphoenolpyruvate 2,3-phosphonomutase. Other names in common use include phosphoenolpyruvate-phosphonopyruvate phosphomutase, PEP phosphomutase, phosphoenolpyruvate phosphomutase, PEPPM, and PEP phosphomutase. This enzyme participates in aminophosphonate metabolism.

Phosphoenolpyruvate mutase was discovered in 1988.
