Branched-chain amino acid aminotransferase Branched-chain alpha-keto acid dehydrogenase complex 3-hydroxymethylbutyryl-CoA dehydrogenase. From Wikipedia, the free encyclopedia. This page was last edited on 17 Decemberat Furthermore, the isoenzyme determination has been used extensively as an indication for myocardial damage in heart attacks.

Cystathionine beta synthase Cystathionine gamma-lyase. Common for blood tests CPT — Creatni dehydrogenase Glutaryl-CoA dehydrogenase.

It used to be determined specifically in patients with chest pain but this test has been replaced by troponin. Finally, high CK in the blood may quinaas an indication of damage to CK-rich tissue, such as in rhabdomyolysismyocardial infarctionmyositis and myocarditis.

In other projects Wikimedia Commons. B on 14q32 and M on 19q Malate-aspartate shuttle Glycerol phosphate shuttle. Creatine kinase Crystal structure of human brain-type creatine kinase cfeatin ADP and creatine.


Both mitochondrial CK isoforms are building highly symmetrical octameric structures with 4-fold symmetry. 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.

Isoenzyme patterns differ in tissues. Molecular and Cellular Biology portal.

Methionine adenosyltransferase Adenosylhomocysteinase regeneration of methionine: There are, therefore, three different isoenzymes: Clinically, creatine kinase is assayed in blood tests as a marker of damage of CK-rich tissue such as in myocardial infarction heart attackrhabdomyolysis severe muscle breakdownmuscular dystrophyautoimmune myositidesand acute kidney injury. Troponin measurement has largely replaced this in many hospitals, although some centers still rely on CK-MB.

Creatine kinase

Mitochondrial membrane transport protein Mitochondrial permeability transition pore Mitochondrial carrier. Carnitine palmitoyltransferase I Long-chain-fatty-acid—CoA ligase.

Cholesterol side-chain cleavage enzyme Steroid beta-hydroxylase Aldosterone synthase Frataxin. The genes for these subunits are located on different chromosomes: Ferritin Serum iron Transferrin saturation Total iron-binding capacity Transferrin Transferrin receptor. PCr is not only an energy buffer but also a cellular transport form of energy between subcellular sites of energy ATP production mitochondria and glycolysis and those of energy utilization ATPases.

Creatine kinase – Wikipedia

Protein-histidine pros-kinase Protein-histidine tele-kinase Histidine kinase. Cleveland Clinic Journal of Medicine. Allosteric regulation Cooperativity Enzyme inhibitor Enzyme activator. The functional entity of the latter two mitochondrial CK isoforms is an octamer consisting of four dimers each. ETH Zurich and by Dr. In addition to those three cytosolic CK isoforms, there are two mitochondrial creatine kinase isoenzymes, the ubiquitous and sarcomeric form.


Ribose-phosphate diphosphokinase Thiamine diphosphokinase. Retrieved from ” https: CK is often determined routinely in a medical laboratory. Protein metabolismsynthesis and catabolism enzymes. Essential amino acids are in Capitals. 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.

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.
