Enzymes 6-phosphofructokinase isoenzymes

A different problem results from deficiency of enzymes of glycolysis such as phosphofructokinase (see Box 20-D), phosphoglycerate rnutase, and pyruvate kinase. Lack of one isoenzyme of phosphoglycerate rnutase in muscle leads to intolerance to strenuous exercise/ A deficiency in pyruvate kinase is one of the most common defects of glycolysis in erythrocytes and leads to a shortened erythrocyte lifetime and hereditary hemolytic anemia.s...
