PPC — Zea mays

Summary

ZM00001EB309660, designated ZmPPC (also known as ZmPEPC-2, PPC2, PPC1, and several other synonyms), is a maize gene on chromosome 7 that encodes a phosphoenolpyruvate carboxylase (EC 4.1.1.31), a member of the PEP_COase bacterial/plant-type family. The encoded enzyme possesses phosphoenolpyruvate carboxylase activity and is associated with protein phosphorylated amino acid binding and protein binding. ZmPPC is linked to a wide array of biological processes, including CAM photosynthesis, regulation of gluconeogenesis, malate metabolism, nitrogen utilization, lateral root branching, aerenchyma formation, and response to starvation. It is also associated with numerous agronomic traits such as grain moisture content, photosynthetic rate, water use efficiency, heat tolerance, biomass yield, chlorophyll content, and carbon isotope discrimination. The protein localizes to the cytosol, chloroplast stroma, mitochondria, and plasmodesmata.
