LITERATURE

diphosphate + oxaloacetate = phosphate + phosphoenolpyruvate + CO2

3 entries

diphosphate + oxaloacetate = phosphate + phosphoenolpyruvate + CO2

the mechanism involves the formation of pentavalent diphosphoenolpyruvate which then is carboxylated to yield oxaloacetate and diphosphate

diphosphate + oxaloacetate = phosphate + phosphoenolpyruvate + CO2

in the reverse direction the addition of CO2 is only to the si face of phosphoenolpyruvate
