WebIn human, six distinct thiolases have been identified. Each of these thiolases is different from the other with respect to sequence, oligomeric state, substrate specificity and … WebJul 26, 2012 · Thiolases are a ubiquitous group of enzymes that are involved in biosynthetic and degradative pathways of lipid metabolism. In the last step of the β-oxidation pathway [4] , degradative thiolases catalyze the shortening of the fatty acid chains by degrading 3-keto acyl CoA to form acetyl CoA and a shortened acyl CoA species ( Figure 1 ).
WebJan 1, 2014 · Thiolase is a conserved enzyme present in the three domains of life (Bacteria, Archaea and Eukarya). This ubiquitous enzyme catalyzes the reversible thiolytic cleavage of 3-ketoacyl-CoA into acyl-CoA and acetyl-CoA, a two-step reaction involving a covalent intermediate formed with a catalytic cysteine. WebMnTMPyP pretreatment also restored I/R-induced suppressed activities of mitochondrial aldehyde dehydrogenase, 3-ketoacyl-CoA thiolases, and adenosine triphosphate synthase.
WebNov 21, 2006 · The sub-cellular location of enzymes of fatty acid β-oxidation in plants is controversial. In the current debate the role and location of particular thiolases in fatty … Thiolases, also known as acetyl-coenzyme A acetyltransferases (ACAT), are enzymes which convert two units of acetyl-CoA to acetoacetyl CoA in the mevalonate pathway. Thiolases are ubiquitous enzymes that have key roles in many vital biochemical pathways, including the beta oxidation pathway … See more Thiolases are a family of evolutionarily related enzymes. Two different types of thiolase are found both in eukaryotes and in prokaryotes: acetoacetyl-CoA thiolase (EC 2.3.1.9) and 3-ketoacyl-CoA thiolase (EC 2.3.1.16). … See more Mammalian nonspecific lipid-transfer protein (nsL-TP) (also known as sterol carrier protein 2) is a protein which seems to exist in two … See more Most enzymes of the thiolase superfamily are dimers.
