Figure 1 shows a simple model of GSNO metabolism and its interactions with other molecules in cells where different reactions including S -nitrosylation, S -transnitrosation, and S -glutathionylation are involved (Hogg, S -nitrosylation as this kind of post-translational modification can alter the function of the affected proteins (Astier et al., Figure 1 1 -SH) through a process of S -transnitrosation between proteins
