Purification and properties of the phosphoglycerate mutase isozymes from the mouse.
The two homodimeric isozymes of phosphoglycerate mutase have been purified from murine kidney and muscle. No differences were observed in the Michaelis-Menten constant for the substrate 2-phospho-D-glycerate, in molecular weight, temperature and pH optima, when the purified isozymes were compared. The isozymes differ in their inhibition constants for phosphoenolpyruvate, in their Michaelis constants for 3-phospho-D-glycerate and 2,3-bisphospho-D-glycerate, their thermal and pH lability and in their sensitivity towards mercury ions.
