An overview of mechanisms of redox signaling - PMC - PubMed …
Redox signaling requires an electrophile (a molecule that attracts electrons) reacting with a nucleophile (a molecule that will give up electrons). There are thus two major types of reactions in redox signaling. One involves reactions in which the electrophile takes electrons away leaving the nucleophile in a more oxidized state.

Reactive oxygen species and cell signaling. Review☆
Feb 1, 2024 · Superoxide signaling is thought to affect the redox state of transition metal ion complexes in proteins and can be regulated by SODs. Examples include superoxide-dependent disruption of the iron‑sulfur (Fe S) cluster in aconitase, and inactivation of the Fe S form of mitochondrial glutaredoxin 2.
