Key message

• Osppc2a, Osppc4, Comparison of plant-type phosphoenolpyruvate carboxylases from rice: identification of two plant-specific regulatory regions of the allosteric enzyme., One is the N-terminal extension; replacement of the extension of Osppc2a (cytosolic) with that from Osppc4 reduced the aspartate and glutamate sensitivities to about one-tenth of the wild-type values but left the PEP affinity unaffected
• Osppc2a, Osppc4, Comparison of plant-type phosphoenolpyruvate carboxylases from rice: identification of two plant-specific regulatory regions of the allosteric enzyme., Replacement of the lysine of Osppc2a with glutamate-alanine lowered the PEP affinity to a quarter of the wild-type level (down to the Osppc4 level), without affecting inhibitor sensitivity
