Heteronuclear NMR spectroscopy and other experiments indicate that the true substrate of the E1 component of 2-oxo acid dehydrogenase complexes is not lipoic acid but the lipoyl domain of the E2 component. E1 can recognize the lipoyllysine residue as such, but reductive acylation ensues only if the domain to which the lipoyl group is attached is additionally recognized by virtue of a mosaic of contacts distributed chiefly over the half of the domain that contains the lipoyl-lysine residue. The lipoyl-lysine residue may not be freely swinging, as supposed hitherto, but may adopt a preferred orientation pointing towards a nearby loop on the surface of the lipoyl domain. This in turn may facilitate the insertion of the lipoyl group into the active site of E1, where reductive acylation is to occur. The results throw new light on the concept of substrate channelling and active-site coupling in these giant multifunctional catalytic machines. ...

The 2-oxoglutarate dehydrogenase (OGDH) complex is an important control point in vertebrate mitochondrial oxidative metabolism, including in the citrate cycle and catabolism of alternative fuels including glutamine. It is subject to allosteric regulation by NADH and the ATP/ADP ratio, and by Ca2+ through binding to the E1 subunit. The latter involves a unique Ca2+-binding site which includes D114ADLD (site 1). Here, we describe three splice variants of E1 in which either the exon expressing this site is replaced with another exon (loss of site 1, LS1) or an additional exon is expressed leading to the insertion of 15 amino acids just downstream of site 1 (Insert), or both changes occur together (LS1/Insert). We show that all three variants are essentially Ca2+-insensitive. Comparison of massive parallel sequence (RNA-Seq) databases demonstrates predominant expression of the Ca2+-sensitive archetype form in heart and skeletal muscle, but substantial expression of the Ca2+-insensitive variants in ...
Mutations on the mitochondrial-expressed Branched Chain α-Keto acid Dehydrogenase Kinase (BCKDK) gene have been recently associated with a novel dietary-treatable form of autism. But, being a mitochondrial metabolism disease, little is known about the impact on mitochondrial performance. Here, we analyze the mitochondrial response to the BCKDK-deficiency in patients primary fibroblasts by measuring bioenergetics, ultra-structural and dynamic parameters. A two-fold increase in superoxide anion production, together with a reduction in ATP-linked respiration and intracellular ATP levels (down to 60%) detected in mutants fibroblasts point to a general bioenergetics depletion that could affect the mitochondrial dynamics and cell fate ...

We previously showed that the oxidation of branched-chain amino acids is increased in rats treated with clofibrate [Paul and Adibi (1980) J. Clin. Invest. 65, 1285-1293]. Two subsequent studies have reported contradictory results regarding the effect of clofibrate treatment on gene expression of branched-chain keto acid dehydrogenase (BCKDH) in rat liver. Furthermore, there has been no previous study of the effect of clofibrate treatment on gene expression of BCKDH kinase, which regulates the activity of BCKDH by phosphorylation. The purpose of the present study was to investigate the above issues. Clofibrate treatment for 2 weeks resulted in (a) a 3-fold increase in the flux through BCKDH in mitochondria isolated from rat liver, and (b) a modest but significant increase in the activity of BCKDH. However, clofibrate treatment had no significant effect on the mass of E1α, E1β, and E2 subunits of BCKDH or the abundance of mRNAs encoding these subunits. On the other hand, clofibrate treatment ...

Maple syrup urine disease is called maple syrup due to the odor of the urine which is similar to maple syrup. There will be branched chain amino acids present in the urine. Besides that, other symptoms and signs of maple syrup urine disease may include
The branched-chain alpha-keto acid dehydrogenase complex (BCKD) is an inner-mitochondrial enzyme complex involved in the breakdown of the branched-chain amino acids isoleucine, leucine, and valine. The BCKD complex is thought to be composed of a core of 24 transacylase (E2) subunits, and associated decarboxylase (E1), dehydrogenase (E3), and regulatory subunits. This gene encodes the transacylase (E2) subunit. Mutations in this gene result in maple syrup urine disease, type 2. Alternatively spliced transcript variants have been described, but their biological validity has not been determined. [provided by RefSeq, Jul 2008 ...

A review of MSUD literature indicates that infants rarely survive the disorder, and those who do manifest profound neurological abnormality and retardation. A diet which restricts amino acids is necessary in treating the disease. The study examines a rare case of an adolescent with MSUD whose history of aggression and impulsivity was linked to metabolic instability. Hospitalization was required following an episode of disorientation, social withdrawal, and severe cognitive impairment. Selected tests of neuropsychological and cognitive functioning, administered before dietary treatment and ...

3-Methyl-2-oxovaleric acid is a metabolite of isoleucine in man, animals and bacteria. It is the alpha-keto acid analogue of isoleucine. 3-Methyl-2-oxovaleric acid is produced from isoleucine by cytosolic branched chain aminotransferase 1 (EC:2.6.1.42), whereupon it is further degraded by branched chain keto acid dehydrogenase E1 to 2-Methyl-1-hydroxybutyl-ThPP. It is used as a clinical marker for maple syrup urine disease (MSUD). MSUD is caused by a deficiency of the branched-chain -keto acid dehydrogenase compex resulting in an accumulation of branched-chain amino acids and the corresponding -keto-and -hydroxy acids in blood, urine and cerebrospinal fluid causing neurological damage and mental retardation ...

Protozoan parasites of the genus Leishmania are the causative agents of a complex of diseases referred to as leishmaniasis. Leishmania have a digenetic life cycle that involves a sand fly vector (promastigote stage) and a mammalian host (amastigote stage). The parasites reside within very different environmental niches in the two different hosts, and therefore must be able to adapt their energy metabolism to the available carbon and nitrogen sources. Lipoic acid (LA) is a multifaceted molecule, and plays an important role as a water- and fat-soluble antioxidant. LA is also an essential cofactor of the alpha-ketoacid dehydrogenase complexes (alpha-KADHs) and of the glycine cleavage complex (GCC). The alpha-KADHs include the pyruvate dehydrogenase (PDH), branched-chain alpha-ketoacid dehydrogenase (BCKDH) and alpha-ketoglutarate dehydrogenase (alpha-KGDH), each of which is integral to cellular energy metabolism. In some organisms, LA can be acquired through salvage and biosynthesis pathways, and ...

Within the cell free amino acids are probably fermentatively degraded by a pathway that is commonly found in anaerobic hyperthermophilic archaea [6,38]. In a first step amino groups are removed from the carbon skeleton by several distinct aminotransferases, which could be affiliated to class I/II (Tagg_0668), class III (Tagg_0004) and class V (Tagg_1145). The final acceptor of the released amino groups is likely 2-oxoglutarate thereby resulting in the accumulation of glutamate, which is subsequently oxidatively deaminated by the activity of a glutamate dehydrogenase (Tagg_1073). Upon deamination of amino acids the resulting 2-oxoacid derivates can be oxidatively decarboxylated to the respective coenzyme A (CoA) derivates by various 2-oxoacid-ferredoxin oxidoreductases having broad substrate specificity. Genes encoding subunits of all known archaeal 2-oxoacid-ferredoxin oxidoreductases could be identified in the T. aggregans genome and represent pyruvate-ferredoxin oxidoreductase ...
