Common for blood tests CPT — By using this site, you agree to the Terms of Use and Privacy Policy. Adenylate kinase Creatine kinase. Apart from the two mitochondrial CK isoenzyme forms, that is, ubiquitous mtCK present in non-muscle tissues and sarcomeric mtCK present in sarcomeric musclethere are three cytosolic CK isoforms present in the cytosol, depending on the tissue.

Both mitochondrial CK isoforms are building highly symmetrical octameric structures with 4-fold symmetry. The genes for these subunits are located on different chromosomes: Molecular and Cellular Biology portal. In tissues and cells that consume ATP rapidly, especially skeletal musclebut also brain, photoreceptor cells of the retinahair cells of the inner earspermatozoa and smooth musclePCr serves as an energy reservoir for the rapid buffering and regeneration of ATP in situas well as for intracellular energy transport by the PCr shuttle or circuit.

ETH Zurich and by Dr. Amylase Lipase Pancreatic lipase. Branched-chain amino acid aminotransferase Branched-chain alpha-keto acid dehydrogenase complex Enoyl-CoA hydratase 3-hydroxyisobutyryl-CoA hydrolase 3-hydroxyisobutyrate dehydrogenase Methylmalonate semialdehyde dehydrogenase.


It used to be determined specifically in patients with chest pain but this test has been replaced by troponin. CK is often craetin routinely in a medical laboratory. In other projects Wikimedia Commons. Cholesterol side-chain cleavage enzyme Steroid beta-hydroxylase Aldosterone synthase Frataxin. Finally, high CK in the blood may be an indication of damage to CK-rich tissue, such as in rhabdomyolysismyocardial infarctionmyositis and myocarditis.

Qujnasa ammonia-lyase Urocanate hydratase Formiminotransferase cyclodeaminase.

Views Read Edit Quinaza history. This means creatine kinase in blood may be elevated in a wide range of clinical conditions including the use of medication such as statins ; endocrine disorders such as hypothyroidism ; [11] and skeletal muscle diseases and disorders including malignant hyperthermia[12] and neuroleptic malignant syndrome.

Creatine kinase in the blood may be high in health and disease. Furthermore, the isoenzyme determination has been used extensively as an indication for myocardial damage in heart attacks. Creatine kinase Crystal structure of human brain-type creatine kinase with ADP and creatine. Saccharopine dehydrogenase Glutaryl-CoA dehydrogenase. The functional entity of the latter two mitochondrial CK isoforms is an octamer consisting of four dimers each.

Branched-chain amino acid aminotransferase Branched-chain alpha-keto acid dehydrogenase complex 3-hydroxymethylbutyryl-CoA dehydrogenase. CK-BB is predominantly creatij in brain and cdeatin muscle, including vascular and uterine tissue. UTP—glucosephosphate uridylyltransferase Galactosephosphate uridylyltransferase. Chemical pathology EC 2. In the cells, the “cytosolic” CK enzymes consist of two subunits, which can be either B brain type or M muscle type.

Creatine kinase – Wikipedia

Ribose-phosphate diphosphokinase Thiamine diphosphokinase. The mitochondrial creatine kinase CK m is present in the mitochondrial intermembrane space, where it regenerates phosphocreatine PCr from mitochondrially generated ATP and creatine Cr imported from the cytosol. There are, therefore, three different isoenzymes:
