Biological function summary

RuBisCO initiates the Calvin Cycle acting as the enzyme that drives the conversion of inorganic carbon dioxide into organic compounds. The protein exists as part of a larger complex comprising eight large subunits and eight small subunits which contribute to its catalytic effectiveness. This function is important for the synthesis of sugars that support plant growth. The enzyme also plays a role in photorespiration by fixing oxygen although this process is less efficient compared to carbon fixation.

Pathways

RuBisCO plays a central role in the carbon fixation pathway of photosynthesis enabling the conversion of light energy into chemical energy gained from carbohydrates. It is critical for the Calvin Cycle and interacts with other proteins such as glyceraldehyde-3-phosphate dehydrogenase during the pathway. Secondly RuBisCO contributes to the photorespiratory pathway though its affinity for oxygen can cause competition with NADP+ reduction during photosynthesis. Interactions with RuBisCO activase are necessary for maintaining its activity under varying conditions.
