WebPhosphoenolpyruvate carboxylase (PEP carboxylase), the key enzyme of C 4 metabolism, is highly regulated. In a darkened leaf, this enzyme has low activity. In this state, the affinity … WebOct 15, 2015 · We found that glucose deprivation stimulated re-wiring of the tricarboxylic acid (TCA) cycle and early steps of gluconeogenesis to promote glucose-independent cell proliferation. Glucose limitation promoted the production of phosphoenolpyruvate (PEP) from glutamine via the activity of mitochondrial PEP-carboxykinase (PCK2).
