Peroxynitrite formed by mitochondrial NO synthase promotes mitochondrial Ca2+ release.


Mitochondria contribute to the maintenance of the intracellular Ca2+ homeostasis by taking up and releasing the cation via separate and specific pathways. The molecular details of the release pathway are elusive but its stimulation by the cross-linking of some vicinal thiols and consequently NAD+ hydrolysis are known. Thiol cross-linking and NAD+ hydrolysis… (More)
