Creatine kinase – Wikipedia

Ribose-phosphate diphosphokinase Thiamine diphosphokinase. Citrate synthase Aconitase Isocitrate dehydrogenase Oxoglutarate dehydrogenase complex Succinyl coenzyme A synthetase Fumarase Malate dehydrogenase. 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.

Protein metabolismsynthesis and catabolism enzymes.

Creatine kinase

Carnitine palmitoyltransferase I Long-chain-fatty-acid—CoA ligase. Creatine kinase Crystal structure of human brain-type creatine kinase quiasa ADP and creatine. By using this site, you agree to the Terms of Use and Privacy Policy. Apart from the two mitochondrial CK isoenzyme forms, that is, ubiquitous mtCK quinasq in non-muscle tissues and sarcomeric mtCK present in sarcomeric musclethere are three cytosolic CK isoforms present in the cytosol, depending on the tissue.

This page was last edited on 17 Decemberat The mitochondrial creatine cratin 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. Carbamoyl phosphate synthetase I Ornithine transcarbamylase N-Acetylglutamate synthase.


Cystathionine beta synthase Cystathionine gamma-lyase. Adenylate kinase Creatine kinase. Mitochondrial membrane transport protein Mitochondrial qquinasa transition pore Mitochondrial carrier. Amylase Lipase Pancreatic lipase. CK is often determined routinely in a medical laboratory. A number of genuine CK structures have been solved by high-resolution electron microscopy and protein X-ray crystallography by the two research groups led by Dr.

Histidine ammonia-lyase Urocanate hydratase Formiminotransferase cyclodeaminase. Exercise increases the outflow of creatine kinase to the blood stream for up to a week, and this is the most common cause of high CK in blood. From Wikipedia, quinaasa free encyclopedia. B on 14q32 and M on 19q 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.

Views Read Edit View history. Guanidinoacetate N-methyltransferase Creatine kinase. Retrieved from ” https: Finally, high CK in the blood may be an indication of damage to CK-rich tissue, such as in rhabdomyolysismyocardial infarctionmyositis and myocarditis.

Aspartate transaminase Glutamate dehydrogenase Pyruvate dehydrogenase complex. This quinasaa 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.

Branched-chain amino acid aminotransferase Branched-chain alpha-keto acid dehydrogenase complex quuinasa dehydrogenase. The functional entity of the latter two mitochondrial CK isoforms is an octamer consisting of four dimers each. The atomic structure of cytosolic brain-type BB-CK was solved at 1. Essential amino acids are in Capitals. Allosteric regulation Cooperativity Enzyme inhibitor Enzyme activator. Isoenzyme patterns differ in tissues.


Both mitochondrial CK isoforms are building highly symmetrical octameric structures with 4-fold symmetry. CK-BB is predominantly expressed in brain and smooth muscle, including vascular and uterine tissue. Troponin measurement has largely replaced this in many hospitals, although some centers still rely on CK-MB. Ferritin Serum iron Transferrin saturation Total iron-binding capacity Transferrin Transferrin receptor.

Quknasa Clinic Journal of Medicine. The genes for these subunits are located on different chromosomes: Common for blood tests CPT — 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.

In the cells, the “cytosolic” CK enzymes consist of two subunits, which can be either B brain type or M muscle type. Biochimica et Biophysica Acta.

Furthermore, the isoenzyme determination has been used extensively as an indication for myocardial damage in heart attacks. Ornithine aminotransferase Ornithine decarboxylase Agmatinase. There are, therefore, three different isoenzymes:
