.... In addition, the CoA ester malonyl-CoA has an important role in regulating fatty acid oxidation, secondary to inhibiting CPT (carnitine palmitoyltransferase) 1, a key enzyme involved in mitochondrial fatty acid uptake. Alterations in malonyl-CoA synthesis by ACC (acetyl-CoA carboxylase) and degradation by MCD...

...R.W. Brownsey; A.N. Boone; J.E. Elliott; J.E. Kulpa; W.M. Lee Acetyl-CoA carboxylase (ACC) catalyses the formation of malonyl-CoA, an essential substrate for fatty acid synthesis in lipogenic tissues and a key regulatory molecule in muscle, brain and other tissues. ACC contributes importantly...

... molecule that controls myocardial fatty acid oxidation is malonyl-CoA, which inhibits uptake of fatty acids into the mitochondria. The levels of malonyl-CoA in the heart are controlled both by its synthesis and degradation. Three enzymes, namely AMP-activated protein kinase (AMPK), acetyl-CoA carboxylase...

... carboxylase (ACC) exists in mammals as two isoforms, termed ACC-1 and ACC-2 (also known as ACC-α and ACC-β). AMPK phosphorylates and inactivates both isoforms at the equivalent site. Knockout mice, and other approaches, suggest that the malonyl-CoA produced by ACC-2 is exclusively involved in regulation...

...S. Eaton; K. Fukumoto; N. Paladio Duran; A. Pierro; L. Spitz; P. A. Quant; K. Bartlett Carnitine palmitoyltransferase I is assumed to be rate limiting for β-oxidation in all tissues. However, the concentration of malonyl-CoA in heart and muscle is high and is enough to completely inhibit β...

...V. A. Zammit; N. T. Price; F. Fraser; V. N. Jackson Elucidation of the membrane topology of carnitine palmitoyltransferase (CPT) I showed that the extreme N-terminus is involved in determining the sensitivity of the liver (L) isoform to malonyl-CoA and suggested that interaction between the two...

...J. D. McGarry Although malonyl-CoA was first recognized as a central component in the regulation of hepatic ketogenesis, its inhibitory effect on mitochondrial carnitine palmitoyltransferase I (CPT I) has come to be viewed as a key element in fuel sensing in a variety of body tissues...

... it is deduced that this ESE sequence is partly responsible for the formation of the three transcripts. The protein encoded by cis -spliced mRNA of rat COT is inhibited by malonyl-CoA and etomoxir. cDNA species encoding full-length wild-type COT and one double mutant COT were expressed in Saccharomyces...
