WebPhosphoglucose isomerase (PGI) is the second enzyme in the glycolytic pathway and catalyzes an aldose-ketose isomerization. Outside the cell, PGI has been found to function as both a cytokine and as a growth factor. The human pgi gene was cloned and the expressed enzyme was purified to homogeneity. Isomorphous crystals were obtained … WebThe Phosphoglucose Isomerase Colorimetric Assay kit provides a simple and direct procedure for measuring PGI activity in a variety of samples. PGI activity is determined by a coupled enzyme assay in which fructose-6-phosphate is converted by PGI to glucose-6-phosphate. Glucose-6-phosphate is subsequently oxidized to form a product, which reacts …
