|
| Authors: | K Tornheim J M Lowenstein |
| Abstract: | Previously reported inhibitions of heart lactate dehydrogenase (Guppy, M., and Hochachka, P.W. (1978) J. Biol. Chem. 253, 8465-8469) and muscle pyruvate kinase (Kemp, R.G. (1973) J. Biol. Chem. 248, 3963-3967) by creatine phosphate are due to oxalate which is a contaminant found in some commercial preparations of creatine phosphate. |
