Mitochondrial morphogenesis is a key process of cell physiology. It is essential for the proper function of this double membrane-delimited organelle, as it ensures the packing of the inner membrane in a very ordered pattern called cristae. In yeast,

Eisenia fetida earthworms were exposed to electromagnetic field (EMF) at a mobile phone frequency (900 MHz) and at field levels ranging from 10 to 120 V m-1 for a period of two hours (corresponding to specific absorption rates ranging from 0.13 to 9.

The involvement of subunit 6 (a) in the interface between yeast ATP synthase monomers has been highlighted. Based on the formation of a disulfide bond and using the unique cysteine 23 as target, we show that two subunits 6 are close in the inner mito

Background information. The yeast mitochondrial F1Fo-ATP synthase is a large complex of 600 kDa that uses the proton electrochemical gradient generated by the respiratory chain to catalyse ATP synthesis from ADP and Pi. For a large range of organisms

Publikováno v: Journal of Biological Chemistry. 279:40392-40399

Subunits e and g of Saccharomyces cerevisiae ATP synthase are required to maintain ATP synthase dimeric forms. Mutants devoid of these subunits display anomalous mitochondrial morphologies. An expression system regulated by doxycycline was used to mo
