Malonyl-CoA decarboxylase was purified from goose uropygial gland, reduced, carboxymethylated, and digested with trypsin. Several peptides were purified by high performance liquid chromatography and their amino acid sequences determined. Oligonucleotide probes were prepared based on their amino acid sequences. Size-selected RNA from the goose uropygial gland was used to construct cDNA libraries...
Long chain fatty acid biosynthesis proceeds through a condensation between acetyl coenzyme A and malonyl coenzyme A (1,2) as has now been shown in fatty acid synthetase systems from animal (3), plant (4), and microbial (5-7, Sl) sources. With studies on extracts of Escherichia coli, in which the major product is vaccenic acid, Lennarz, Light, and Bloch (7) have shown and we have confirmed (8) t...
Engineering metabolic biosynthetic pathways has enabled the microbial production of many useful chemicals. However, pathway productivities and yields are often limited by metabolic imbalances. Synthetic regulatory circuits have been shown to be able to balance engineered pathways, improving titers and productivities. Here we developed a negative feedback regulatory circuit based on a malonyl-Co...
Abnormally high rates of fatty acid oxidation and low rates of glucose oxidation are important contributors to the severity of ischemic heart disease. Malonyl coenzyme A (CoA) regulates fatty acid oxidation by inhibiting mitochondrial uptake of fatty acids. Malonyl CoA decarboxylase (MCD) is involved in the decarboxylation of malonyl CoA to acetyl CoA. Therefore, inhibition of MCD may decrease ...

Goodwin, Gary W., and Heinrich Taegtmeyer. Regulation of fatty acid oxidation of the heart by MCD and ACC during contractile stimulation. Am. J. Physiol. 277 (Endocrinol. Metab. 40): E772–E777, 1999.—We tested the hypothesis that the level of malonyl-CoA, as well as the corresponding rate of total fatty acid oxidation of the heart, is regulated by the opposing actions of acetyl-CoA carboxylase ...
Malonyl coenzyme A (malonyl-CoA) is an important precursor for the synthesis of natural products, such as polyketides and flavonoids. The majority of this cofactor often is consumed for producing fatty acids and phospholipids, leaving only a small amount of cellular malonyl-CoA available for producing the target compound. The tuning of malonyl-CoA into heterologous pathways yields significant p...
The functional molecular sizes of the protein(s) mediating the carnitine palmitoyltransferase I (CPT I) activity and the [14C]malonyl-CoA binding in purified outer-membrane preparations from rat liver mitochondria were determined by radiation-inactivation analysis. In all preparations tested the dose-dependent decay in [14C]malonyl-CoA binding was less steep than that for CPT I activity, sugges...
A procedure is described for the rapid measurement of the activity of mitochondrial-outer-membrane carnitine palmitoyltransferase (CPTo) and peroxisomal carnitine palmitoyltransferase (CPTp) in digitonin-permeabilized hepatocytes. CPTo activity was determined as the tetradecylglycidate (TDGA)-sensitive malonyl-CoA-sensitive CPT activity, whereas CPTp activity was monitored as the TDGA-insensiti...
Recently, our laboratory reported the involvement of cytochrome be in the elongation of hepatic microsomal fatty acids (Keyes, S. R., Alfano, J. A., Jansson, I., and Cinti, D. L. (1979) J. Biol. Chem. 254,7778-7784). In this paper, a correlation between the rates of ba reoxidation in the presence of malonyl-CoA and malonyl-CoA incorporation measured under various conditions was demonstrated, th...
