Serum creatine kinase

Creatine Kinase (CK) (ATP: Creatine N-phosphotransferase EC 2.7.3.2) is also known as phosphocreatine kinase (CPK). CK is mainly found in skeletal muscle, brain and heart muscle. Creatine kinase is of higher value in the diagnosis of acute myocardial infarction. It is usually found in the cytoplasm and mitochondria of the heart, muscle, and brain of animals. It is an important kinase 1,2 that is directly related to intracellular energy movement, muscle contraction, and ATP regeneration. It reversibly catalyzes creatine and ATP. Between transphosphorylation reactions.
