Journal ArticleDOI
The ATP synthase is involved in generating mitochondrial cristae morphology
Patrick Paumard,Jacques Vaillier,Bénédicte Coulary,Jacques Schaeffer,Vincent Soubannier,David M. Mueller,Daniel Brèthes,Jean-Paul di Rago,Jean Velours +8 more
TL;DR: A model is proposed of the assembly of ATP synthase dimers, taking into account the oligomerization of the yeast enzyme and earlier data on the ultrastructure of mitochondrial cristae, which suggests that the association of mitochondria of yeast cells deficient in either subunits e or g is involved in the control of the biogenesis of the inner mitochondrial membrane.
Journal ArticleDOI
The Mitochondrial F0F1-ATPase proton pump is required for function of the proapoptotic protein Bax in yeast and mammalian cells
TL;DR: The findings imply that an intact F0F1-ATPase in the inner membrane of mitochondria is necessary for optimal function of Bax in both yeast and mammalian cells.
Journal ArticleDOI
The modulation in subunits e and g amounts of yeast ATP synthase modifies mitochondrial cristae morphology.
Geneviève Arselin,Jacques Vaillier,Bénédicte Salin,Jacques Schaeffer,Marie-France Giraud,Alain Dautant,Daniel Brèthes,Jean Velours +7 more
TL;DR: The data demonstrate that the inner structure of mitochondria depends upon the ability of ATP synthase to make supramolecular structures, which is fully reversible upon removal of doxycycline.
Journal ArticleDOI
The GxxxG motif of the transmembrane domain of subunit e is involved in the dimerization/oligomerization of the yeast ATP synthase complex in the mitochondrial membrane.
Geneviève Arselin,Marie-France Giraud,Alain Dautant,Jacques Vaillier,Daniel Brèthes,Bénédicte Coulary-Salin,Jacques Schaeffer,Jean Velours +7 more
TL;DR: The data show the involvement of the dimerization motif of subunit e in the formation of supramolecular structures of mitochondrial ATP synthases and are in favour of the existence in the inner mitochondrial membrane of associations of ATP synthase whose masses are higher than those of ATP synthesis dimers.
Journal ArticleDOI
Identification of a Nuclear Gene (FMC1) Required for the Assembly/Stability of Yeast Mitochondrial F1-ATPase in Heat Stress Conditions
Linnka Lefebvre-Legendre,Jacques Vaillier,Houssain Benabdelhak,Jean Velours,Piotr P. Slonimski,Jean-Paul di Rago +5 more
TL;DR: Western blot analysis showed that Fmc1p is a soluble protein located in the mitochondrial matrix that is required for the proper folding/stability or functioning of Atp12p in heat stress conditions.
