PEPC — Medicago truncatula

Summary

MTR_2G076670, also known as MtPPC1 or PEPC, encodes a phosphoenolpyruvate carboxylase, an enzyme with phosphoenolpyruvate carboxylase activity that also exhibits protein phosphorylated amino acid binding and protein binding. This gene is associated with a wide range of biological processes including nitrogen fixation, nodulation, phloem sucrose loading, TCA cycle, fermentation, cellular response to phosphate starvation, salt response, and brassinosteroid-mediated signalling. It has been linked to traits such as photosynthetic rate, drought tolerance, glucose and carbohydrate content, nitrate uptake, root morphology, and seedling growth and development. The encoded protein is localised to the cytosol, chloroplast stroma, mitochondria, plasmalemma, apoplast, and plant-type vacuole. Studies of related genes in other species connect the family to phosphate starvation response, salt stress tolerance, and anaplerobic metabolism.
