EC Number Natural Substrates Organism Comment (Nat. Sub.) Natural Products Comment (Nat. Pro.) Rev. Reac.
4.1.1.31 Phosphoenolpyruvate + CO2 Zea mays three PEPC isoforms: one is the C4-form PEPC, which plays a cardinal role in the initial CO2-fixation of C4 photosynthesis by capturing atmospheric CO2 into C4-dicarboxylic acids, the second one is a C3-housekeeping PEPC, which plays anaplerotic roles by replenishing C4-dicarboxylic acids in the citric acid cycle for synthesis of cell constituents, the root-form PEPC plays various anaplerotic roles, including providing the carbon skeletons for nitrogen assimilation, pH maintenance, and osmolarity regulation ?
