Glutaric acidemia type II (GAII), also known as multiple acyl-CoA dehydrogenase deficiency, is an autosomal recessive inborn error of amino acid and fatty acid metabolism. We report a case of GAII with novel electron transfer flavoprotein (ETF)-A mutations in a 2-year-old female with thalassemia minor. The patient developed an episode of hypoglycemia and hypotonicity on the postnatal first day. Laboratory investigations revealed elevations of multiple acyl carnitines indicating glutaric acidemia type II in newborn screening analysis...

The coordination of valeric acid (VA), glutaric acid (GA) and tricarballylic acid (TA) with Fe-OH on the Fe3 O4 nanoparticle surface has been systematically studied to elucidate the effect of COOH, molecular configuration and ligand concentration on the coordination by the combining use of attenuated total reflectance Fourier transform infrared (ATR-FTIR) and thermogravimetric analysis (TGA). The results show that the binding ability of the acids increases with the increase of the COOH number. Multiple conformations coexist for the dicarboxylic and tricarboxylic acid coordinated on the iron oxide NPs...

Muscle weakness is a nonspecific finding of myopathy of any etiology that include iatrogenic, toxic, endocrinological, infectious, immunologic, and metabolic disorders. Among the metabolic myopathies glutaric aciduria type II (GAII) is an autosomal recessively inherited rare disorder of fatty acid and amino acid metabolisms. The late onset form is heterogeneous in terms of symptomatology and severity and for the cases that chronic manifestations of lipid storage myopathy are the only clues for the disease, differential diagnosis can be challenging...

Glutaric acid is a promising alternative chemical to phthalate plasticizer, since it can be produced by the bioconversion of lysine. Though recent studies have enabled high-yield production of its precursor, 5-aminovaleric acid (AMV), glutaric acid production via the AMV pathway has been limited by need for cofactors. Introduction of NAD(P)H oxidase (Nox) with GabTD enzyme remarkably diminished the demand for NAD+ . Supply of oxygen through vigorous shaking had a significant effect on the conversion of AMV with a reduced requirement of NAD+ ...

The dicarboxylic acid glutarate is an important building-block gaining interest in the chemical and pharmaceutical industry. Here, a synthetic pathway for fermentative production of glutarate by the actinobacterium Corynebacterium glutamicum has been developed. The pathway does not require molecular oxygen and operates via lysine decarboyxylase followed by two transamination and two NAD-dependent oxidation reactions. Using a genome-streamlined L-lysine producing strain as basis, metabolic engineering was performed to enable conversion of L-lysine to glutarate in a five-step synthetic pathway comprising lysine decarboxylase, putrescine transaminase and γ-aminobutyraldehyde dehydrogenase from Escherichia coli and GABA/5AVA amino transferase and succinate/glutarate semialdehyde dehydrogenase either from C...

The complexation of hexavalent plutonyl Pu(vi) with N,N,N',N'-tetramethyl-3-oxa-glutar-amide (TMOGA) and its carboxylate analogs, N,N-dimethyl-3-oxa-glutaramic acid (DMOGA) and oxydiacetic acid (ODA), has been studied in 1.0 M NaClO4 by absorption spectrophotometry and density functional theory (DFT). Both 1 : 1 and 1 : 2 complexes of Pu(vi) with TMOGA, DMOGA and ODA have been identified and their stability constants were obtained and compared with those of hexavalent U(vi) and pentavalent Np(v). The resultant stability constants indicate that the ability of the three ligands to complex with Pu(vi) decreases in the order of ODA > DMOGA > TMOGA...

Multiple acyl-CoA dehydrogenase deficiency (MADD) or glutaric aciduria type II (GAII) is a clinically heterogeneous disorder affecting fatty acid and amino acid metabolism. Presentations range from a severe neonatal form with hypoglycemia, metabolic acidosis, and hepatomegaly with or without congenital anomalies to later-onset lipid storage myopathy. Genetic testing for MADD traditionally comprises analysis of ETFA, ETFB, and ETFDH. Patients may respond to pharmacological doses of riboflavin, particularly those with late-onset MADD due to variants in ETFDH...

There is a considerable interest in the use of structurally stable and catalytically active enzymes, such as cytochrome C (Cyt C), in the pharmaceutical and fine chemical industries. However, harsh process conditions, such as temperature, pH, and presence of organic solvents, are the major barriers to the effective use of enzymes in biocatalysis. Herein, we demonstrate the suitability of bio-based ionic liquids (ILs) formed by the cholinium cation and dicarboxylate-based anions as potential media for enzymes, in which remarkable enhanced activity and improved stability of Cyt C against multiple stresses were obtained...

BACKGROUND: Glutaric aciduria type 1, a deficiency of glutaryl-CoA dehydrogenase, causes an accumulation of neurotoxic metabolites glutaric acid and 3-hydroxyglutaric acid (3-HGA). Testing of these analytes is routinely done by GC-MS but seldom account for interference from isomers or compounds with similar ion transitions. We developed a liquid chromatography tandem mass spectrometry method that accurately measures 3-HGA in urine and plasma specimens, while utilizing similar reagents and instrumentation used for the routine performance of amino acid and acylcarnitine analysis in determining the diagnosis of several metabolic disorders...

Glutaric acid is one of the promising C5 platform compounds in the biochemical industry. It can be produced chemically, through the ring-opening of butyrolactone followed by hydrolysis. Alternatively, glutaric acid can be produced via lysine degradation pathways by microorganisms. In microorganisms, the overexpression of enzymes involved in this pathway from E. coli and C. glutamicum has resulted in high accumulation of 5-aminovaleric acid. However, the conversion from 5-aminovaleric acid to glutaric acid has resulted in a relatively low conversion yield for unknown reasons...

The deficiency of the enzyme glutaryl-CoA dehydrogenase, known as glutaric acidemia type I (GA-I), leads to the accumulation of glutaric acid (GA) and glutarilcarnitine (C5DC) in the tissues and body fluids, unleashing important neurotoxic effects. l-carnitine (l-car) is recommended for the treatment of GA-I, aiming to induce the excretion of toxic metabolites. l-car has also demonstrated an important role as antioxidant and anti-inflammatory in some neurometabolic diseases. This study evaluated GA-I patients at diagnosis moment and treated the oxidative damage to lipids, proteins, and the inflammatory profile, as well as in vivo and in vitro DNA damage, reactive nitrogen species (RNS), and antioxidant capacity, verifying if the actual treatment with l-car (100 mg kg-1  day-1 ) is able to protect the organism against these processes...
