In addition to enzymatic methods, a nonenzymatic pathway for the production of NO from NO₂ has been reported. This sort of NO production is favored by low pH, e.g., in the apoplast of the growing seeds, where NO can be released from a protonated form of NO₂, i.e., nitrous acid (HNO₂). Another possible mechanism is the release of NO from S-nitrosoglutathione (GSNO). In the peroxisomes, both NO and the NO-derived peroxynitrite can interact with glutathione to synthesize GSNO (Neill et al. 2003; Courtois et al. 2008; Wilson et al. 2008; Palavan-Unsal and Arisan 2009).
