The enzyme carnitine-acylcarnitine translocase (CACT) is involved in the transport of long-chain fatty acids into mitochondria. CACT deficiency is a life-threatening, recessively inherited disorder of lipid beta-oxidation which manifests in early infancy with hypoketotic hypoglycemia, cardiomyopathy, liver failure, and muscle weakness. We report here the(More)
Environmental and occupational exposure to a large number of chemicals occurs at various stages throughout human life. Many of these are devoid of toxicity, but some could pose a significant health risk, i.e. the exposure to environmental xenobiotic metals as lead, mercury (Sinicropi et al. 2010a; Carocci et al. 2014), cadmium, etc. In particular, lead has(More)
Environmental contamination has exposed humans to various metal agents, including mercury. It has been determined that mercury is not only harmful to the health of vulnerable populations such as pregnant women and children, but is also toxic to ordinary adults in various ways. For many years, mercury was used in a wide variety of human activities. Nowadays,(More)
The sequences are presented of cDNAs encoding five related proteins from the nematode worm, Caenorhabditis elegans. Three of them can be recognised as the homologues of the ADP/ATP, phosphate and oxoglutarate/malate carrier proteins that have been found in the inner membranes of mitochondria in other species. These carrier proteins, and the uncoupling(More)
The oxoglutarate carrier (OGC) belongs to the mitochondrial carrier family and plays a key role in important metabolic pathways. Here, site-directed mutagenesis was used to conservatively replace lysine 122 by arginine, in order to investigate new structural rearrangements required for substrate translocation. K122R mutant was kinetically characterized,(More)
The structural and dynamic features of the fourth transmembrane segment of the mitochondrial oxoglutarate carrier were investigated using site-directed spin labeling and electron paramagnetic resonance (EPR). Using a functional carrier protein with native cysteines replaced with serines, the 18 consecutive residues from S184 to S201 which are believed to(More)
The structures of the first and the second transmembrane segment of the bovine mitochondrial oxoglutarate carrier (OGC) were studied by circular dichroism (CD) and nuclear magnetic resonance (NMR) spectroscopies. Peptides 21-46 and 78-108 of its primary sequence were synthesized and structurally characterized in membrane-mimetic environments. CD data showed(More)
The citrate (tricarboxylate) carrier transports citrate (or other tricarboxylates) across the inner membranes of mitochondria in an electroneutral exchange for malate (or other dicarboxylic acids). We have determined the sequence of the human citrate transporter gene from overlapping genomic clones generated by polymerase chain reactions by use of primers(More)
