Function
function
Through the carboxylation of phosphoenolpyruvate (PEP) it forms oxaloacetate, a four-carbon dicarboxylic acid source for the tricarboxylic acid cycle.
Catalytic activity
- oxaloacetate + phosphate = hydrogencarbonate + phosphoenolpyruvate
Cofactor
Activity regulation
By light-reversible phosphorylation.
Pathway
Photosynthesis; C4 acid pathway.
