Triose-phosphateisomerase (TPI) in plant chloroplasts is an important enzyme involved in calvin cycle in photosynthesis. Acting on the transformation between glyceraldehyde phosphate and dihydroxyacetone phosphate, dihydroxyacetone phosphate can quickly penetrate the chloroplast envelope and enter the cytoplasm, where it is gradually transformed into sucrose. CheKine™ Micro Triose-Phosphate Isomerase (TPI) Activity Assay Kit can detect plant tissues In this kit, TPI converts dihydroxyacetone phosphate into glyceraldehyde-3-phosphate, and glyceraldehyde-3-phosphate and NAD react with glyceraldehyde-3-phosphate dehydrogenase to generate glyceric acid-3-phosphate and NADH. The absorbance change at 340 nm reflects the activity of TPI.

β-Xylosidase (EC 3.2.1.37) exists in organisms such as plants, bacteria, and fungi. It is a key enzyme that catalyzes the degradation of xylan-based hemicelluloses, and the product xylose can serve as a carbon source for microbial fermentation. Additionally, β-xylosidase can be used as a biobleaching agent in the paper industry, offering environmental benefits over traditional bleaching methods and possessing broad application value. CheKine™ Mirco β-Xylosidase (β-X) Activity Assay Kit offers a simple, convenient, and rapid approach for assessing β-Xylosidase activity, which is suitable for plant tissue, bacteria, and fungi samples. The principle involves β-xylosidase catalyzing the production of p-nitrophenol from p-nitrophenyl-β-D-xyloside. p-Nitrophenol exhibits a characteristic absorption peak at 405 nm. By measuring the rate of increase in absorbance at 405 nm, the β-xylosidase activity can be calculated.

Fructose -1,6- diphosphatase (FBP), also known as fructose -1,6- diphosphatase, plays a key role in gluconeogenesis and the synthesis of sucrose, an assimilate of photosynthesis. Catalyze fructose-1,6- diphosphate and water to produce fructose-6- phosphate and inorganic phosphorus. CheKine™ Micro Fructose 1,6-Bisphosphatase (FBP) Activity Assay Kit can detect animal and plant tissues, cells, plasma, serum or other liquid samples. In this kit, FBP catalyzes fructose-1,6-diphosphate and water toproduce fructose-6-phosphate and inorganic phosphorus. Glucose-6-phosphate isomerase and glucose-6-phosphate dehydrogenase added in the reaction system catalyze glucose-6-phosphate and NADPH in turn, and the activity of FBP can becalculated by measuring the increase rate of NADPH at 340 nm.
