Overview
Primary disorders of mitochondrial ATP synthase belong to the most severe mitochondrial diseases. They can becaused by heteroplasmic mtDNA mutations in ATP6 gene that affect ability of enzyme to synthesise ATP, or bymutations in nuclear genes encoding factors essential for biosynthesis and assembly of the catalytic F1-part of theenzyme. In the latter case the cellular content of the enzyme decreases to ≤30 %. In both types of defects lowproduction of ATP appears to be associated with increased mitochondrial ROS production related to elevated levelsof mitochondrial membrane potential.
Key words:
Mitochondrial diseases, cardiomyopathy, ATP synthase, oxidative phosphorylation, respiratory chaincomplexes.
