ENZYME entry: EC 2.7.1.26

Accepted Name
riboflavin kinase
Alternative Name(s)
flavokinase
RFK
Reaction catalysed
ATP + riboflavin <=> ADP + FMN + H(+)
Comment(s)
  • The cofactors FMN and FAD participate in numerous processes in all organisms, including mitochondrial electron transport, photosynthesis, fatty-acid oxidation, and metabolism of vitamin B6, vitamin B12 and folates.
  • While monofunctional riboflavin kinase is found in eukaryotes, some bacteria have a bifunctional enzyme that exhibits both this activity and that of EC 2.7.7.2.
  • In Bacillus subtilis, ATP can be replaced by other phosphate donors but with decreasing enzyme activity in the order ATP > dATP > CTP > UTP.
