Reaction: Semiquinone reacts with oxygen

- in pathway: TP53 regulates transcription of several additional cell death genes whose specific roles in p53-dependent apoptosis remain uncertain
Semiquinone spontaneously reacts with oxygen to revert to a quinone state and produces superoxide anion (Oppermann 2007, Porte et al. 2009).
Reaction - small molecule participants:
O2.- [cytosol]
1,2-Naphthoquinone [cytosol]
