FMN cofactor: oxidoreductases
- Supports redox reactions across metabolism
- Includes pyridoxine 5'-phosphate oxidase — B6 activation depends on B2
- Riboflavin deficiency impairs the whole flavoprotein set
Drugs with this mechanism (1)
- FMN — Riboflavin-derived redox cofactor; accepts electrons in mitochondrial complex I and other flavoprotein reactions.
Self-check
- Activation of which vitamin depends on this FMN-dependent oxidase?
Vitamin B6. - Does riboflavin deficiency affect only one FMN-dependent enzyme?
No; it impairs the whole flavoprotein set.
