background the malonyl-coa decarboxylase (mcd, ec.4.1.1.9) enzyme regulates malonyl-coa levels. the effect of aerial parts extracts of urtica dioica (ud) on mcd is poorly understood. objectives the present experiment was undertaken to evaluate the effect of ud aerial parts extracts on mcd level. materials and methods in this experimental study, two groups of rats were used: normal and hyperglyc...

Anaerobic decarboxylation of malonate to acetate was studied with Sporomusa malonica, Klebsiella oxytoca, and Rhodobacter capsulatus. Whereas S. malonica could grow with malonate as sole substrate (Y = 2.0 g.mol-l) , malonate decarboxylation by K. oxytoca was coupled with anaerobic growth only in the presence of a cosubstrate, e.g. sucrose or yeast extract (Y, = 1.1-1.8 g.mol malonate-1). R. ca...

BACKGROUND Acute pharmacological inhibition of cardiac malonyl coenzyme A decarboxylase (MCD) protects the heart from ischemic damage by inhibiting fatty acid oxidation and stimulating glucose oxidation. However, it is unknown whether chronic inhibition of MCD results in altered cardiac function, energy metabolism, or ischemic cardioprotection. METHODS AND RESULTS Mcd-deficient mice were prod...

Malonyl coenzyme A is synthesized by transacylating S-malonyl-N-decanoyl cysteamine with coenzyme A. A simplified procedure for the preparation of S-malonyl-N-decanoyl cysteamine, using cysteamine as starting material, is described.

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...

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 ...

that cardiac decompensation can be avoided in MCD-deficient patients. Finally, by analogy with fatty acid oxidation disorders such as medium-chain acyl-CoA dehydrogenase deficiency (13), one may conclude that knowledge of the diagnosis will improve outcome because early intervention is then possible in catabolic episodes that otherwise may lead to metabolic derange-ment. It therefore seems reas...
