The Pyruvate Phosphate Dikinase (PPDK) Activity Assay Kit is widely used in research to measure the enzymatic activity of PPDK, which plays a critical role in metabolic pathways. It is particularly valuable in studying C4 and CAM plants, where PPDK is essential for carbon fixation and energy metabolism. The kit is also employed in agricultural research to understand plant responses to environmental stress, such as drought or high temperatures, by analyzing PPDK activity levels. Additionally, it aids in biochemical studies to explore the enzyme’s role in gluconeogenesis and its potential applications in bioengineering for improving crop efficiency. Its use extends to enzymology research, providing insights into enzyme kinetics and regulatory mechanisms.
