General description

Riboflavin 5′-monophosphate (FMN) is highly soluble in water. Flavins are considered as blue-light absorbing dyes.

Application

Riboflavin 5′-monophosphate (FMN) is used as a prosthetic group by oxidoreductase (one and two electron transfer) enzymes such as NADH dehydrogenases, nitric oxide synthases, and nitrilotriacetate monooxygenases. Riboflavin 5′-monophosphate is used as a substrate to study the specificity and kinetics of FMN phosphohydrolases. FMN is used to study molecular sensing based gene regulation by riboswitches.
Riboflavin 5′-monophosphate sodium salt hydrate has been used:
  • in the study to examine FMN (flavin mononucleotide) photo-reduction in aqueous solutions
  • to immobilize on titanium oxide modified carbon fibre to determine its electrochemical behavior
  • in flavin identification

Biochem/physiol Actions

Riboflavin 5′-monophosphate (FMN) acts as a cofactor in flavoproteins and possess biological activity in enzymes and photoreceptors.

Preparation Note

Prepared by the enzymatic hydrolysis of flavin adenine dinucleotide.
