Accepted name:
phosphoenolpyruvate mutase
Other names:
PEP phosphomutase
phosphoenolpyruvate phosphomutase
phosphoenolpyruvate-phosphonopyruvate phosphomutase
PEP mutase
Systematic name:
phosphoenolpyruvate 2,3-phosphonomutase



Involved in the biosynthesis of the C-P bond, although the equilibrium greatly favours phosphoenolpyruvate.
