The Kinetics of Phosphoglucoisomerase
Abstract
Phosphoglucoisomerase (isomerase) is present in most tissues at very high levels of activity. Because of its strategic position in relation to alternate metabolic pathways, its kinetics are of interest. The kinetics are also of practical concern in connection with the use of glucose 6phosphate to measure enzyme systems which produce glucose 6-phosphate, since isomerase, an ubiquitous contaminant, could distort the results if it diverted some of the product to fructose 6-phosphate.
