Sodium dodecyl sulfate-denatured biotinyl proteins will bind (/sup 14/C)methyl avidin which remains bound through polyacrylamide gel electrophoresis. The method has been used to demonstrate the presence of two high molecular weight subunit forms of acetyl CoA carboxylase in rat liver cytoplasm, both of which are precipitated by ...

Acetyl-coenzyme A (CoA) carboxylase catalyzes the first step in the biosynthesis of fatty acids in bacteria and eukaryota. This enzyme is the target of drug design for treatment of human metabolic diseases and of herbicides acting specifically on the eukaryotic form of the enzyme in grasses. Acetyl-CoA ...

Extracts from human leukocytes have been examined for the enzymes of de novo fatty acid biosynthesis. These extracts do not catalyze the synthesis of long-chain fatty acids because they lack acetyl CoA carboxylase, the first enzyme unique to the fatty acid synthesis pathway.Since these cells cannot form malonyl ...

Acetyl-CoA carboxylase [ACCase; acetyl-CoA:carbon-dioxide ligase (ADP-forming), EC 6.4.1.2] catalyzes the ATP-dependent carboxylation of acetyl CoA to produce malonyl CoA. In plants, malonyl CoA is needed for plastid localized fatty acid biosynthesis ...
2',3'-O-(2,4,6-Trinitrophenyl) adenosine 5'-triphosphate (TNP-ATP) is a fluorescent analogue of ATP. MgTNP-ATP was found to be an allosteric activator of pyruvate carboxylase that exhibits competition with acetyl CoA in activating the enzyme. There is no evidence that MgTNP-ATP binds to the MgATP substrate binding site of the enzyme. ...
The activities of four biotin enzymes, acetyl-coenzyme A (CoA) carboxylase, 3-methylcrotonyl-CoA carboxylase, pyruvate carboxylase, and propionyl-CoA carboxylase, and the accumulation of six biotin-containing polypeptides were determined during development of somatic ...
The pathway of autotrophic CO2 fixation was studied in the phototrophic bacterium Chloroflexus aurantiacus and in the aerobic thermoacidophilic archaeon Metallosphaera sedula. In both organisms, none of the key enzymes of the reductive pentose phosphate cycle, the reductive citric acid cycle, and the reductive acetyl coenzyme A ...
Acetyl coenzyme A (CoA) carboxylase activity of whole tissue homogenates and chloroplast preparations was analyzed as the acetyl-CoA-dependent incorporation of [14C]bicarbonate into an acid-stable product. The absolute requirement for ATP and MgCl2, the complete ...
The central nervous system mediates energy balance (energy intake and energy expenditure) in the body; the hypothalamus has a key role in this process. Recent evidence has demonstrated an important role for hypothalamic malonyl CoA in mediating energy balance. Malonyl CoA is generated by the carboxylation of acetyl ...
Prolactin (PRL) stimulates an increased rate of incorporation of ({sup 14}C)acetate and ({sup 3}H)glucose into lipids in cultured mammary gland explants from 10-to 14-day-pregnant mice. This response is biphasic with an early increase occurring from 6 through 12 h, and an additional increase from 16 to 24 h. Enzymes likely to be rate limiting to this process include acetyl ...

Cinnamon bark ( CINNAMOMUM ZEYLANICUM) is used extensively as an antimicrobial material and currently is being increasingly used in Europe by people with type II diabetes to control their glucose levels. In this paper we describe the action of cinnamon oil, its major component, TRANS-cinnamaldehyde, and an analogue, 4-hydroxy-3-methoxy- TRANS-cinnamaldehyde against bacterial ...
Pyruvate carboxylase (PC) is a conserved metabolic enzyme with important cellular functions. We report here crystallographic and cryoEM studies of S. aureus PC (SaPC) in complex with acetyl-CoA, an allosteric activator, as well as mutagenesis, biochemical and structural studies of the biotin binding site of its carboxyltransferase (CT) domain. The ...
Conditions are described under which monomeric (/sup 14/C)methyl avidin binds to SDS-denatured biotin enzymes and remains bound through polyacrylamide gel electrophoresis. The location of radioactive proteins on the dried gel was determined by fluorography and their identity was established by subunit molecular weight. The relative quantity of bound radioactive avidin, stoichiometrically ...
The phototrophic bacterium Chloroflexus aurantiacus uses a yet unsolved 3-hydroxypropionate cycle for autotrophic CO(2) fixation. It starts from acetyl-CoA, with acetyl-CoA and propionyl-CoA carboxylases acting as carboxylating enzymes. In a first cycle, (S)-malyl-CoA is formed from acetyl-CoA and 2 molecules of ...

The suborder Corynebacterianeae comprises bacteria like Mycobacterium tuberculosis and Corynebacterium glutamicum, and these bacteria contain in addition to the linear fatty acids, unique ?-branched ?-hydroxy fatty acids, called mycolic acids. Whereas acetyl-coenzyme A (CoA) carboxylase activity is required to provide malonyl-CoA for ...
