malonyl-coa decarboxylase (mcd) is an enzyme involved in the decarboxylation of malonyl-coa to acetyl-coa. in order to explore the hypothesis that the changing plant materials’ mcd activity level can serve as therapy to diabetics, the effect of teucrium polium compounds was studied in a diabetic rat model. in this experimental study, two groups of rats, a control and a diabetic group, each incl...
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...
The structural genes of the sodium ion pump methylmalonyl-coenzyme A (CoA)-decarboxylase from Veillonella parvula have recently been cloned on three overlapping plasmids (pJH1, pJH20, and pJH40) and sequenced. To synthesize the complete decarboxylase in Escherichia coli, the genes were fused in the correct order (mmdADECB) on a single plasmid (pJH70). A DNA region upstream of mmdA apparently se...
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...
The goal of this study was to test the relationship between malonyl-CoA concentration and its turnover measured in isolated rat hearts perfused with NaH(13)CO(3). This turnover is a direct measurement of the flux of acetyl-CoA carboxylation in the intact heart. It also reflects the rate of malonyl-CoA decarboxylation, i.e. the only known fate of malonyl-CoA in the heart. Conditions were selecte...
AIMS This study was undertaken to evaluate the oxalate-degrading activity in several Lactobacillus species widely used in probiotic dairy and pharmaceutical preparations. Functional characterization of oxalyl-CoA decarboxylase and formyl-CoA transferase in Lactobacillus acidophilus was performed in order to assess the possible contribution of Lactobacillus in regulating the intestinal oxalate h...
Malonyl-CoA decarboxylase (E.C.4.1.1.9) catalyzes the conversion of malonyl-CoA to acetyl-CoA. Although the metabolic role of this enzyme has not been fully defined, it has been reported that its deficiency is associated with mild mental retardation, seizures, hypotonia, cadiomyopathy, developmental delay, vomiting, hypoglycemia, metabolic acidosis, and malonic aciduria. Here, we isolated a cDN...
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...

We have characterized the expression of potential acetyl-CoA-generating genes (acetyl-CoA synthetase, pyruvate decarboxylase, acetaldehyde dehydrogenase, plastidic pyruvate dehydrogenase complex and ATP-citrate lyase), and compared these with the expression of acetyl-CoA-metabolizing genes (heteromeric and homomeric acetyl-CoA carboxylase). These comparisons have led to the development of testa...
