Acetylation prevents the breakdown of glutathione, and S-acetylglutathione does not require energy expenditure to be cleaved to reduced glutathione once it crosses the cell wall

189 Further, ME1 treated with the inhibitor (piperazine-1-pyrrolidine-2,5-dione) has little effect on normal rat intestinal epithelial cells but strongly suppresses human CRC cell growth by targeting ME1 NADP + -binding site and reducing the NADPH level

The relevance of this enzyme is illustrated by the fact that global SOD2 deficiency leads to neonatal death in mice ( c plus cytochrome c oxidase system ( Although the dismutation of superoxide by SOD2 is a predominant source of H 2 O 2 , there are other reactions that directly generate H 2 O 2 in mitochondria
