چکیده

Biosynthetic studies with (13)C-labelled acetates and methionine revealed that the infamous, food-related toxin bongkrekic acid from Burkholderia gladioli is a polyketide with acetate-derived beta-branches and a carboxylate terminus derived from the methyl group of an acetate.

Bongkrekic acid. An inhibitor of the adenine nucleotide translocase of mitochondria.

The antibiotic bongkrekic acid is shown to inhibit the phosphorylation of added ADP coupled with either the reactions of the respiratory chain or the dismutation of oc-ketoglutarate in mammalian mitochondria. It also prevents the utilization of ATP for energy-linked cation transport and in energy dissipation by uncoupling agents. However, bongkrekic acid does not inhibit the Mg++-requiring ATPa...

Reversible Inhibition of Adenine Nucleotide Translocation by Long Chain Acyl-CoA Esters in Bovine Heart Mitochondria and Inverted Submitochondrial Particles

Isolated beef heart mitochondria incubated with atractylate and oleoyl coenzyme A at concentrations below 5 PM produced an immediate and significant inhibition of adenine nucleotide translocation, whereas inhibition by bongkrekic acid, which required preincubation with the mitochondria, was less rapid and a concentration of 50 pin was required for maximum effect. In sonicated submitochondrial p...

The adenine nucleotide translocase modulates oligomycin-induced quenching of pyranine fluorescence in submitochondrial particles.

Incorporation of the fluorescent, nonpermeant pH indicator pyranine into submitochondrial particles (pyranine-SMP) permitted monitoring of intravesicular pH changes brought about by proton translocation due to oxidation of respiratory chain substrates or to hydrolysis of ATP. Addition of oligomycin to beef heart pyranine-SMP was followed by a pH-independent quenching of pyranine fluorescence. Q...

Evaluation of Porin Interaction with Adenine Nucleotide Translocase and Cyclophilin-D Proteins after Brain Ischemia and Reperfusion

Objective (s) Porin is a mitochondrial outer membrane channel, which usually functions as the pathway for the movement of various substances in and out of the mitochondria and is considered to be a component of the permeability transition (PT) pore complex that plays a role in the PT. We addressed the hypothesis that porin interacts with other mitochondrial proteins after ischemic injury. Mater...

Mitochondrial ND5 gene variation associated with encephalomyopathy and mitochondrial ATP consumption.

Mitochondrial encephalomyopathy and lactic acidosis with strokelike episodes (MELAS) is a severe young onset stroke disorder without effective treatment. We have identified a MELAS patient harboring a 13528A-->G mitochondrial DNA (mtDNA) mutation in the Complex I ND5 gene. This mutation was homoplasmic in mtDNA from patient muscle and nearly homoplasmic (99.9%) in blood. Fibroblasts from the pa...
