FMN cofactor: Complex I
- Riboflavin → FMN, the electron-entry flavin of Complex I (NADH → ubiquinone)
- First stop of the respiratory chain; riboflavin deficiency shows up as energy-pathway failure
Drugs with this mechanism (1)
- FMN — Riboflavin-derived redox cofactor; accepts electrons in mitochondrial complex I and other flavoprotein reactions.
