The localization of acyl coenzyme A-carnitine acyltransferases in rat liver cells.
The distribution of acetyl coenzyme A-carnitine acetyltransferase (EC 2.3.1.7) and of palmityl-CoA-carnitine palmityltransferase (EC 2.3.1) in subcellular fractions of rat liver has been studied. The distribution of carnitine pahnityltransferase in the different fractions obtained with differential centrifugation and with centrifugation in a steep sucrose gradient correlated closely with the di...
متن کاملStructure and function of carnitine acyltransferases.
Carnitine acyltransferases catalyze the exchange of acyl groups between carnitine and coenzyme A (CoA). These enzymes include carnitine acetyltransferase (CrAT), carnitine octanoyltransferase (CrOT), and carnitine palmitoyltransferases (CPTs). CPT-I and CPT-II are crucial for the beta-oxidation of long-chain fatty acids in the mitochondria by enabling their transport across the mitochondrial me...
متن کاملCharacterization and properties of carnitine acyltransferases.
lysine metabolism has been measured in rats fed a diet low in trimethyl-lysine and carnitine (Davis & Hoppel, 1983, 1986). Under these steady-state conditions, the total body trimethyl-lysine content is similar to the total body carnitine content. The tissue distribution of peptide-linked and free trimethyl-lysine shows that approximately 68% of the total trimethyl-lysine is present in skeletal...
متن کاملEvidence of two catalytically active carnitine medium/long chain acyltransferases in rat liver peroxisomes.
Peroxisomal matrix proteins were extracted from the highly purified peroxisomes with sodium pyrophosphate, and the membranes were sedimented by high speed centrifugation. Biochemical marker enzyme analyses revealed a quantitative release of a number of well-known peroxisomal matrix proteins from the purified peroxisomes. In contrast, carnitine medium/long chain acyltransferase activity, assayed...
متن کاملUltrastructural immunocytochemical localization of fibronectin in the early chick embryo.
Fibronectin was localized using peroxidase and biotin-avidin-ferritin techniques in developmental stages of the chick embryo from laying to primitive streak formation. The primary location of fibronectin at all stages examined was the basal lamina of the epiblast and its associated extracellular material. The remaining tissues showed little or no immunochemical deposit. At the primitive streak ...
