2.7.1.1 S-nitrosoglutathione hexokinase is particularly susceptible to protein structure modifications when exposed to even low concentrations of S-nitrosoglutathione. Biologically relevant [S-nitrosoglutathione]/[hexokinase] causes a significant decrease in Vmax with glucose (but not with fructose), along with oxidation of 5 Met and nitration of 4 Tyr. Preincubation of hexokinase with glucose abrogates the effect of S-nitrosoglutathione whereas fructose is ineffective Saccharomyces cerevisiae
