It is shown that under conditions of experimental limitation of coronary blood flow in rabbits the intensity of radioactive label (32P) incorporation into creatine phosphate lowers essentially. This evidences for inhibition of creatine phosphorylation in mitochondria under ischemia due to a decrease in the activity of a mitochondrial isoenzyme of creatine kinase.
