Bioenergetic and structural consequences of allotopic expression of subunit 8 of yeast mitochondrial ATP synthase. The hydrophobic character of residues 23 and 24 is essential for maximal activity and structural stability of the enzyme complex.

Abstract excerpt

Subunit 8 (Y8), a mitochondrially encoded subunit of the F0 sector of the F1F0-ATP synthase is essential for oxidative phosphorylation. We have previously introduced the technique of allotopic expression to study the structure/function of Y8, whereby an artificial Y8 gene is expressed in the nucleus of cells lacking a functional mitochondrial Y8, thus generating assembly of a functional F1F0-ATPase complex. In...
