Mitochondrial respiratory chain supercomplexes are destabilized in Barth Syndrome patients.
Mutations in the human TAZ gene are associated with Barth Syndrome, an often fatal X-linked disorder that presents with cardiomyopathy and neutropenia. The TAZ gene encodes Tafazzin, a putative phospholipid acyltranferase that is involved in the remodeling of cardiolipin, a phospholipid unique to the inner mitochondrial membrane. It has been shown that the disruption of the Tafazzin gene in yea...
متن کاملMitochondrial Cristae Shape Determines Respiratory Chain Supercomplexes Assembly and Respiratory Efficiency
Respiratory chain complexes assemble into functional quaternary structures called supercomplexes (RCS) within the folds of the inner mitochondrial membrane, or cristae. Here, we investigate the relationship between respiratory function and mitochondrial ultrastructure and provide evidence that cristae shape determines the assembly and stability of RCS and hence mitochondrial respiratory efficie...
متن کاملQuestioning the functional relevance of mitochondrial supercomplexes by time-resolved analysis of the respiratory chain.
Mitochondria are the powerhouses of eukaryotic cells as they feed metabolism with its major substrate. Oxidative-phosphorylation relies on the generation, by an electron/proton transfer chain, of an electrochemical transmembrane potential utilized to synthesize ATP. Although these fundamental principles are not a matter of debate, the emerging picture of the respiratory chain diverges from the ...
متن کاملCoenzyme q and the respiratory chain: coenzyme q pool and mitochondrial supercomplexes.
Two alternative models of organization of the mitochondrial electron transport chain (mETC) have been alternatively favored or questioned by the accumulation evidences of different sources, the solid model or the random collision model. Both agree in the number of respiratory complexes (I-IV) that participate in the mETC, but while the random collision model proposes that Complexes I-IV do not ...
متن کاملPhosphatidylethanolamine and Cardiolipin Differentially Affect the Stability of Mitochondrial Respiratory Chain Supercomplexes
The mitochondrial inner membrane contains two non-bilayer-forming phospholipids, phosphatidylethanolamine (PE) and cardiolipin (CL). Lack of CL leads to destabilization of respiratory chain supercomplexes, a reduced activity of cytochrome c oxidase, and a reduced inner membrane potential Δψ. Although PE is more abundant than CL in the mitochondrial inner membrane, its role in biogenesis and ass...
