WebJan 13, 2012 · The thionitrate stabilizes by spontaneous nucleophilic attack of a second neighboring cysteine thiol group by formation of a disulfide bridge and release of nitrite. Another possibility could be the direct generation of NO by the thionitrate ( Fung, 2004 ) but it is unclear to this date whether this process requires transition metals ( Beretta ...
