Investigating The Multiple Enzyme Complex In Carotenoid Biosynthesis Pathway
Abstract
In nature, plant carotenoids are 40-carbon isoprenoids with polyene chains that may have double bonds. They are vital components of all photosynthetic organisms. Carotenoids play several roles in the plant cell, including photosynthesis, pigmentation, phytohormone synthesis, signaling and photoprotection. They also give many fruits, flowers, and roots their vivid orange, yellow, or red colors. These pigments serve as precursors to the manufacture of vitamin A in humans, which supports healthy vision, strengthens immunity, and nourishes the skin. Additionally, they operate as dietary antioxidants to help prevent the development of long-term conditions like cancer, macular degeneration, UV-induced skin damage, infectious and cardiovascular diseases. The carotenoid biosynthesis pathway involving the enzymatic processes has been thoroughly characterized. It is uncertain how these enzymes are physically arranged in the carotenoid metabolic pathway within the plant cells. Therefore, to understand how these proteins interact with one another at the molecular level, it is essential to investigate the subcellular architecture of these enzymes. This will make it easier to comprehend the post-translational regulation mechanism of carotenoid metabolism.
