Coenzyme A (CoA) is an important cofactor (acyl-chain carrier) for many cellular functions including the citrate cycle and fatty acid biosynthesis and metabolism. Vitamin B5, also known as pantothenate is the precursor for CoA biosynthesis. Pantothenate synthesis takes place in plants, fungi and some bacteria, whereas animals salvage pantothenate from diet and CoA biosynthesis from pantothenate is present in most organisms. Plasmodium falciparum utilises pantothenate from host and converts it to CoA (CoA biosynthesis). In contrast, the Coccidians Toxoplasma gondii and Neospora caninum possess the four enzymes required for the generation of pantothenate from the branched chain amino acid valine. Except dephospho-CoA kinase (2.7.1.24), all other enzymes involved in the downstream conversion of pantothenate to CoA are present. Dephospho-CoA kinase, an enzyme present in P. falciparum is missing in T. gondii and N. caninum gene models. It has previously been suggested that T. gondii ...

Holocarboxylase synthetase (HCS, human) and BirA (Escherichia coli) are biotin protein ligases that catalyze the ATP-dependent attachment of biotin to apocarboxylases. Biotin attachment occurs on a highly conserved lysine residue within a consensus sequence (Ala/Val-Met-Lys-Met) that is found in carboxylases in most organisms. Numerous studies have indicated that HCS and BirA, as well as biotin protein ligases from other organisms, can attach biotin to apocarboxylases from different organisms, indicating that the mechanism of biotin attachment is well conserved. In this study, we examined the cross-reactivity of biotin attachment between human and bacterial biotin ligases by comparing biotinylation of p-67 and BCCP87, the biotin-attachment domain fragments from human propionyl-CoA carboxylase and E. coli acetyl-CoA carboxylase, respectively. While BirA has similar biotinylation activity toward the two substrates, HCS has reduced activity toward bacterial BCCP87 relative to its native substrate, p-67.

Malotilate is a new drug suggested for use in chronic liver diseases. It is shown here to prevent liver damage caused by CCl4. The concomitant administration of malotilate with CCl4 significantly decreased hydroxyproline accumulation in the liver, liver prolyl 4-hydroxylase and liver and serum galactosylhydroxylysyl glucosyltransferase activities. However, it had no effect on the daily urinary hydroxyproline excretion or the hydroxyproline content of the skin, liver or lungs in normal young growing rats. It also had no specific inhibitory effect on hydroxyproline synthesis or secretion in fibroblast cultures, and did not affect the amount of procollagen-alpha 1(I)-specific mRNAs in these cultures. Thus it seems to have no direct inhibitory effect on collagen metabolism. In addition to inhibition of liver collagen accumulation, malotilate was also able to prevent the development of morphological changes in the liver such as focal necrosis, fatty infiltration and inflammatory changes. It also ...

Malonyl Coenzyme A: A coenzyme A derivative which plays a key role in the fatty acid synthesis in the cytoplasmic and microsomal systems.

Acetyl-CoA carboxylase is a biotin-dependent, multifunctional enzyme that catalyzes the first committed step in fatty acid synthesis. The Escherichia coli enzyme is composed of a homodimeric biotin carboxylase, biotinylated biotin carboxyl carrier protein (BCCP), and an α2β2 heterotetrameric carboxyltransferase. Catalysis by acetyl-CoA carboxylase proceeds via two half-reactions. In the first half-reaction, biotin carboxylase catalyzes the ATP-dependent carboxylation of biotin, which is covalently attached to BCCP, to form carboxybiotin. In the second half-reaction, carboxyltransferase transfers the carboxyl group from carboxybiotin to acetyl-CoA to form malonyl-CoA. All biotin-dependent carboxylases are proposed to have a two-site ping-pong mechanism where the carboxylase and transferase activities are separate and do not interact. This posits two hypotheses: either biotin carboxylase and BCCP undergo the first half-reaction, BCCP dissociates, and then BCCP interacts with carboxyltransferase to

Methylmalonic acidemia (MMA), also called methylmalonic aciduria, is an autosomal recessive metabolic disorder. It is a classical type of organic acidemia. The result of this condition is the inability to properly digest specific fats and proteins, which in turn leads to a buildup of a toxic level of methylmalonic acid in the blood. Methylmalonic acidemia stems from several genotypes, all forms of the disorder usually diagnosed in the early neonatal period, presenting progressive encephalopathy, and secondary hyperammonemia. The disorder can result in death if undiagnosed or left untreated. It is estimated that this disorder has a frequency of 1 in 48,000 births, though the high mortality rate in diagnosed cases make exact determination difficult. Methylmalonic acidemias are found with an equal frequency across ethnic boundaries. Depending on the affected gene(s), this disorder may present symptoms that range from mild to life-threatening. Stroke Progressive encephalopathy Seizure Kidney failure ...

N2 - Background: Methylmalonic acidemia (MMA) and propionic acidemia (PA) are related disorders of mitochondrial propionate metabolism, caused by defects in methylmalonyl-CoA mutase (MUT) and propionyl-CoA carboxylase (PCC), respectively. These biochemical defects lead to a complex cascade of downstream metabolic abnormalities, and identification of these abnormal pathways has important implications for understanding disease pathophysiology. Using a multi-omics approach in cellular ...

Coenzyme A is an essential metabolite known for its central role in over one hundred cellular metabolic reactions. In cells, Coenzyme A is synthesized de novo in five enzymatic steps with vitamin B5 as the starting metabolite, phosphorylated by pantothenate kinase. Mutations in the pantothenate kinase 2 gene cause a severe form of neurodegeneration for which no treatment is available. One therapeutic strategy is to generate Coenzyme A precursors downstream of the defective step in the pathway. Here we describe the synthesis, characteristics and in vivo rescue potential of the acetyl-Coenzyme A precursor S-acetyl-4'-phosphopantetheine as a possible treatment for neurodegeneration associated with pantothenate kinase deficiency. ...

Malonyl-CoA:acyl-carrier protein transacylase (MCAT), encoded by the fabd gene, is a key enzyme in type II fatty-acid biosynthesis. It is responsible for transferring the malonyl group from malonyl-CoA to the holo acyl-carrier protein (ACP). Since the type II system differs from the type I system that mammals use, it has received enormous attention as a possible antibiotic target. In particular, only a single isoform of MCAT has been reported and a continuous coupled enzyme assay has been developed. MCAT from Staphylococcus aureus was overexpressed in Escherichia coli and the protein was purified and crystallized. Diffraction data were collected to 1.2 A ° resolution. The crystals belonged to space group P21, with unit-cell parameters a = 41.608, b = 86.717, c = 43.163 A ° , α = γ = 90, β = 106.330 °. The asymmetric unit contains one SaMCAT molecule ...

Methylmalonic Acidemia (MMA) is a metabolic disorder affecting 1 in 25,000 to 48,000 individuals globally. MMA is characterized by increased acidity in the blood and tissues due to toxic accumulation of protein and fat by-products resulting in seizures, strokes, and chronic kidney failure. About 60% of MMA cases stem from mutations in the methylmalonyl CoA mutase (MUT) gene encoding a key enzyme required to break down amino acids and lipids. Previous efforts to develop mice with null mutations in MUT have been unsuccessful, as such mutations result in neonatal death ...

Molybdenum cofactor is a cofactor required for the activity of enzymes such as sulfite oxidase, xanthine oxidoreductase, and aldehyde oxidase. It is a coordination complex formed between molybdopterin (which, despite the name, does not contain molybdenum) and an oxide of molybdenum. Molybdopterins, in turn, are synthesized from guanosine triphosphate. Molybdenum cofactor functions directly in ethylbenzene dehydrogenase, glyceraldehyde-3-phosphate ferredoxin oxidoreductase, and respiratory arsenate reductase. In animals and plants these enzymes use molybdenum bound at the active site in a tricyclic molybdenum cofactor. All molybdenum-using enzymes so far identified in nature use this cofactor The simplest structure of molybdopterin contains a pyranopterin coordinated to molybdenum. The pyranopterin structure is a fused ring system containing a pyran fused to pterin. In addition, the pyran ring is substituted with two thiols and an alkyl phosphate. In molybdopterin, the thiols coordinate to ...

The citrate lyase activation starts with a 3-dephospho-CoA reacting with ATP and a hydrogen ion through a triphosphoribosyl-dephospho-CoA synthase resulting in a adenine and a 2'-(5'-triphospho-alpha-D-ribosyl)-3'-dephospho-CoA. The latter compound in turn reacts with with a citrate lyase acyl-carrier protein through a apo-citrate lyase phosphoribosyl-dephospho-CoA transferase resulting in the release of a pyrophosphate and a hydrogen ion and a holo citrate lyase acyl-carrier protein.This protein complex can either react with a hydrogen ion and a acetate resulting in the release of a water and an acetyl-holo citrate lyase acyl-carrier protein. The holo acyl-carrier protein creacts with an ATP and an acetate through a citrate lyase synthase resulting in the release of an AMP, a pyrophosphate and an acetyl-holo citrate lyase acyl-ccarrier protein. The holo citrate lyase acyl-carrier protein can also interact with an S-acetyl phosphopantethiene resulting in the release of a 4-phosphopantethiene and ...

Inhibitors of 4'-phosphopantetheine adenylyltransferase (PPAT) were identified through high-throughput screening of the AstraZeneca compound library. One series, cycloalkyl pyrimidines, showed inhibition of PPAT isozymes from several species, with the most potent inhibition of enzymes from Gram-positive species. Mode-of-inhibition studies with Streptococcus pneumoniae and Staphylococcus aureus PPAT demonstrated representatives of this series to be reversible inhibitors competitive with phosphopantetheine and uncompetitive with ATP, binding to the enzyme-ATP complex. The potency of this series was optimized using structure-based design, and inhibition of cell growth of Gram-positive species was achieved. Mode-of-action studies, using generation of resistant mutants with targeted sequencing as well as constructs that overexpress PPAT, demonstrated that growth suppression was due to inhibition of PPAT. An effect on bacterial burden was demonstrated in mouse lung and thigh infection models, but further

SUCLA2-related mitochondrial DNA (mtDNA) depletion syndrome, encephalomyopathic form with methylmalonic aciduria is characterized by onset of the following features in infancy or childhood (median age of onset 2 months; range of onset birth to 6 years): psychomotor retardation, hypotonia, dystonia, muscular atrophy, sensorineural hearing impairment, postnatal growth retardation, and feeding difficulties. Other, less frequent, features include distinctive facial features, contractures, kyphoscoliosis, gastroesophageal reflux, ptosis, choreoathetosis, ophthalmoplegia, and epilepsy (infantile spasms or generalized convulsions). The median survival is 20 years; approximately 30% of affected individuals succumb during childhood. Affected individuals may have hyperintensities in the basal ganglia, cerebral atrophy, and leukoencephalopathy on head MRI. Elevation of methylmalonic acid (MMA) in the urine and plasma is found in a vast majority of affected individuals, although at levels that are far below those

TY - JOUR. T1 - Unexplored interactions between pyrroloquinoline quinone and β-nicotinamide adenine dinucleotide. AU - Jao, Hsi Jung. AU - Tsai, Pei Yi. AU - Wang, Chong Mou. PY - 2007/8/15. Y1 - 2007/8/15. N2 - The interactions between pyrroloquinoline quinone (PQQ) and β-nicotinamide adenine dinucleotide (NAD(H)) characterized by spectral and voltammetric means are reported in this paper. PQQ exists with six major acid-base derivatives in aqueous solutions; the derivative predominating at pH 3, denoted H2Q-, was characterized to be responsible for the electrochemical and photochemical activities of PQQ, such as for the photooxidation of NADH. In contrast, the derivatives predominating at pH , 5, such as HQ2- and Q3-, are responsible for the interaction with NAD+; the equilibrium constant was estimated to be ∼106. Although the basic derivatives are less active in emission compared to H2Q-, incorporating NAD+ can enhance their activity in this respect. The titrations of NAD+ with HQ2- and ...

The correlation of ATP citrate lyase (ACL) and acetyl CoA levels with trichothecene production in Fusarium graminearum was investigated using an inhibitor (precocene II) and an enhancer (cobalt chloride) of trichothecene production by changing carbon sources in liquid medium. When precocene II (30 µM) was added to inhibit trichothecene production in a trichothecene high-production medium containing sucrose, ACL expression was reduced and ACL mRNA level as well as acetyl CoA amount in the fungal cells were reduced to the levels observed in a trichothecene trace-production medium containing glucose or fructose. The ACL mRNA level was greatly increased by addition of cobalt chloride in the trichothecene high-production medium, but not in the trichothecene trace-production medium. Levels were reduced to those level in the trichothecene trace-production medium by addition of precocene II (300 µM) together with cobalt chloride. These results suggest that ACL expression is activated in the presence of

NBIA (neurodegeneration with brain iron accumulation) comprises a heterogeneous group of neurodegenerative diseases having as a common denominator, iron overload in specific brain areas, mainly basal ganglia and globus pallidus. In the past decade a bunch of disease genes have been identified, but NBIA pathomechanisms are still not completely clear. PKAN (pantothenate kinase-associated neurodegeneration), an autosomal recessive disorder with progressive impairment of movement, vision and cognition, is the most common form of NBIA. It is caused by mutations in the PANK2 (pantothenate kinase 2) gene, coding for a mitochondrial enzyme that phosphorylates vitamin B5 in the first reaction of the CoA (coenzyme A) biosynthetic pathway. A distinct form of NBIA, denominated CoPAN (CoA synthase protein-associated neurodegeneration), is caused by mutations in the CoASY (CoA synthase) gene coding for a bifunctional mitochondrial enzyme, which catalyses the final steps of CoA biosynthesis. These two inborn ...

Methane utilization by methanotrophic bacteria is an attractive application for biotechnological conversion of natural or biogas into high-added-value products. Haloalcaliphilic methanotrophic bacteria belonging to the genus Methylomicrobium are among the most promising strains for methane based biotechnology, providing easy and inexpensive cultivation, rapid growth, and the availability of established genetic tools. A number of methane bioconversions using these microbial cultures have been discussed, including the derivation of biodiesel, alkanes, and OMEGA-3 supplements. These compounds are derived from bacterial fatty acid pools. Here, we investigate fatty acid biosynthesis in Methylomicrobium buryatense 5G(B1). Most of the genes homologous to typical Type II fatty acid biosynthesis pathways could be annotated by bioinformatics analyses, with the exception of fatty acid transport and regulatory elements. Different approaches for improving fatty acid accumulation were investigated. These ...

The authors studied a 53 year old woman and her 22 year old son with episodes of paroxysmal muscle cramps and dark urines lasting several hours related to high fat diet and strenuous physical exercise beginning on both at age 14 years. The father, paternal uncle, paternal grandfather and another son of the mother also had paroxysmal muscle cramps. The two studied cases showed normal findings for physical evaluation, blood lactate after ischemic exercise, and muscle histology (light and electron microscopy). The serum creatine kinase was elevated in the son and normal in the mother. However, 72 hour fasting significantly raised the serum creatine kinase level in both cases. Plasma concentration of ketone bodies and acid soluble acyl-carnitine increased normally with prolonged fasting. The biochemical evaluation of the muscle tissue revealed intact anaerobic glycolysis and normal glycogen content but combined partial deficiency of muscle carnitine palmitoyltransferase and carnitine in both ...

Cashews: Tasty Little Gems Carrying Essential Minerals of Life. Cashews naturally come with many vitamins and minerals in them. They are a great on-the-go snack since they are packed to the brim with essential nutrients your body needs. One of these vital nutrients is called Pantothenic Acid, which is otherwise known as the Vitamin B-5. Pantothenic Acid can be found in the living cells of all life forms and is used for various chemical reactions throughout the body. As the Micronutrient Information Center of the Linus Pauling Institute at Oregon State University says, "Pantothenic acid is a component of coenzyme A (CoA), an essential coenzyme in a variety of reactions that sustain life. CoA is required for chemical reactions that generate energy from food (fat, carbohydrates, and proteins). The synthesis of essential fats, cholesterol, and steroid hormones requires CoA…" (Higdon). The key phrase in this quote is: an essential coenzyme in a variety of reactions that sustain life. So quite ...

Tuberculosis continues to be a major cause of morbidity and mortality all over the world. No new drug has been developed in the past 30 yr. Consequently, there is an urgent need to identify new drug targets in mycobacteria and eventually, develop new drugs. The enoyl acyl carrier protein reductase (ENR) from Mycobacterium tuberculosis is one of the key enzymes involved in the type II fatty acid biosynthesis pathway of M. tuberculosis. A series of pyrazoles linked with imidazoles were computationally designed and energy minimized. These ligands were investigated for drug like properties by calculating Lipinski's rule of five using molinspiration. These compounds were docked into the active site of ENR (PDB code, 2H7I) using Argus lab docking software which showed good affinity for the enzyme, when compared with the binging energies of standard drug isoniazid (-8.39kcal/mol.) Among all the designed ligands, the ligand 4 showed more binding energy values (-10.17kcal/mol). Further we planned to ...

The rate of ketogenesis depends upon the activity of three enzymes. One is hormone-sensitive lipase (or triglyceride lipase), which is found in peripheral adipocytes. The other two are acetyl CoA carboxylase and 3-hydroxy-3-methylglutaryl-CoA synthase (HMG CoA synthase), which are found in the liver. Hormone-sensitive lipase catalyzes the conversion of triglycerides to diglycerides for further degradation to the free fatty acids (lipolysis) that serve as substrates for ketogenesis. On the other hand, acetyl CoA carboxylase catalyzes the conversion of acetyl CoA to malonyl CoA, increasing the hepatic level of the primary substrate of fatty acid biosynthesis. Malonyl CoA levels vary in the liver directly according to the rate of fatty acid synthesis and inversely with the rate of fatty acid oxidation. Therefore, malonyl CoA plays a pivotal role in the regulation of ketogenesis. Low levels of malonyl CoA stimulate transport of fatty acids into the mitochondria via the carnitine shuttle for ...

Etomoxir is an irreversible inhibitor of the mitochondrial transport of long-chain fatty acids via blockage of carnitine palmitoyltransferase-I (CPT-1) leading to inhibition of the mitochondrial fatty acid oxidation (FAO). Owing to its inhibitory effect, etomoxir is widely used (40-400 μM) in commercial kits [1,2], however, several studies shed light on the unspecific effect of etomoxir on the mitochondria [3,4]. To assess the specificity of etomoxir on FAO in comparison to its inhibitory effect on mitochondrial respiration involving other mitochondrial pathways, we tested different concentrations of etomoxir (1-200 µM) on permeabilized Huh7 human hepatocellular carcinoma cells and isolated liver mitochondria from mouse, using high-resolution respirometry. Different sources of fatty acids (palmitoylcarnitine, palmityl-CoA + carnitine) were used to test the specific effect of etomoxir towards FAO (F-pathway). We have also investigated the off-target effect of etomoxir on mitochondrial ...

A substance that becomes essential for the working and function of an enzyme other than the protein compounds becomes known as a coenzyme. Coenzymes regularly work as the middle of the road bearers of electrons, molecules or practical gatherings that transfer in the general response. A case of this would be the part of NAD in the move of electrons in certainly coupled oxidation diminishment responses. A coenzyme is a substance that works with a compound to start or help the capacity of the protein. It might get viewed as an assistant particle for a biochemical response. Coenzymes are tiny, non-proteinaceous particles that give an exchange site to a working catalyst. They are moderate bearers of an iota or gathering of particles, enabling a response to happen. Coenzymes don't get considered some portion of a protein's structure; they here and there alluded to as substrates. A sort of cofactor, coenzymes, are fundamental particles that dilemma to compounds and help them work. The key here is that ...

AICAR accumulates in a purH mutant and inhibits the conversion of AIR to HMP, a step catalyzed by the SAM radical protein ThiC (14). The ThiC reaction has been reconstituted in vitro and is not affected by AICAR, indicating the effect in vivo was indirect (26). The present study was initiated to determine the mechanism by which AICAR accumulation inhibits the conversion of AIR to HMP.. The ThiC reaction uses SAM as a cosubstrate and is sensitive to fluctuations in CoA levels in vivo (14, 23, 24, 50). Nutritional studies led to the hypothesis that one metabolic consequence of AICAR accumulation was decreased CoA levels. Metabolite pool measurements confirmed that strains that accumulated AICAR had ∼3-fold-lower total CoA levels than the wild type. Although this level of CoA reduction does not generate a thiamine requirement in an otherwise wild-type strain, conditions that reduce flux through the purine biosynthetic pathway (i.e., adenine in the medium) increase the CoA requirement for thiamine ...

Accepted name: trans-2-decenoyl-[acyl-carrier protein] isomerase. Reaction: a trans-dec-2-enoyl-[acyl-carrier protein] = a cis-dec-3-enoyl-[acyl-carrier protein]. Other name(s): β-hydroxydecanoyl thioester dehydrase; trans-2-cis-3-decenoyl-ACP isomerase; trans-2,cis-3-decenoyl-ACP isomerase; trans-2-decenoyl-ACP isomerase; FabM. Systematic name: decenoyl-[acyl-carrier protein] Δ2-trans-Δ3-cis-isomerase. Comments: While the enzyme from Escherichia coli is highly specific for the 10-carbon enoyl-ACP, the enzyme from Streptococcus pneumoniae can also use the 12-carbon enoyl-ACP as substrate in vitro but not 14- or 16-carbon enoyl-ACPs [3]. ACP can be replaced by either CoA or N-acetylcysteamine thioesters. The cis-3-enoyl product is required to form unsaturated fatty acids, such as palmitoleic acid and cis-vaccenic acid, in dissociated (or type II) fatty-acid biosynthesis..

Whether you're just getting started on your MCAT prep in Golden Gate or you're taking the test tomorrow, we've put together some tips to help raise your score. If you haven't registered for the MCAT, you'll find the list of MCAT testing centers available in Florida. The MCAT is a computer-based test, and is offered on specific dates in January and April through September as a computer-based test at several testing centers in Florida. It's wise to register early. Once you're registered, check out average scores for schools you're applying to. The MCAT is a very important factor in medical school admissions. You should begin your preparation early, even as soon as you know your test date. Ideally, you will want to take the MCAT only once, but it's not uncommon to retake the MCAT. You can take the MCAT three times in one year, but no more than 7 times in your lifetime, and since the exam requires a large investment of time to prepare for, you want to avoid retesting unless you absolutely have to. ...

UNLABELLED: Inhibition of malonyl-coenzyme A decarboxylase (MCD) shifts metabolism from fatty acid towards glucose oxidation, which has therapeutic potential for obesity and myocardial ischemic injury. However, ~40% of patients with MCD deficiency are diagnosed with cardiomyopathy during infancy. AIM: To clarify the link between MCD deficiency and cardiac dysfunction in early life and to determine the contributing systemic and cardiac metabolic perturbations. METHODS AND RESULTS: MCD knockout mice ((-/-)) exhibited non-Mendelian genotype ratios (31% fewer MCD(-/-)) with deaths clustered around weaning. Immediately prior to weaning (18days) MCD(-/-) mice had lower body weights, elevated body fat, hepatic steatosis and glycogen depletion compared to wild-type littermates. MCD(-/-) plasma was hyperketonemic, hyperlipidemic, had 60% lower lactate levels and markers of cellular damage were elevated. MCD(-/-) hearts exhibited hypertrophy, impaired ejection fraction and were energetically compromised (32%
