Biological function summary

Phosphoenolpyruvate carboxylase plays a significant role in the fixation of carbon dioxide contributing to C4 and CAM photosynthesis mechanisms where it takes part in the assimilation of inorganic carbon into organic compounds. It functions as a homotetramer where each subunit contributes to overall enzyme activity. This enzyme not only aids in photosynthesis but also participates in processes like gluconeogenesis and anaplerotic reactions in non-photosynthetic organisms highlighting its diverse roles across species.

Pathways

Phosphoenolpyruvate carboxylase's role is integral to both the C4 and CAM photosynthetic pathways. In these pathways it works alongside other proteins such as Rubisco to mitigate photorespiration and increase photosynthetic efficiency especially under conditions of drought or high temperatures. This enzyme also intersects with the glycolysis and gluconeogenesis pathways connecting to intermediary metabolism through shared molecules like phosphoenolpyruvate and oxaloacetate linking carbohydrate metabolism to broader metabolic networks.
