Biochem/physiol Actions
在益生菌（ATCC 菌株 7469）的生长中具有生物学活性。
Application
Riboflavin 5′-monophosphate (FMN) is used as a prosthetic group by oxidoreductase (one and two electron transfer) enzymes such as NADH dehydrogenase, nitric oxide synthase, and nitrilotriacetate monooxygenase. Riboflavin 5′-monophosphate is used as a substrate to study the specificity and kinetics of FMN phosphohydrolases and to study molecular sensing based gene regulation by riboswitches.

Application
FMN is suitable as a photopolymerization reagent in PAGE by forming free radicals in aqueous solution in the presence of light. FMN photodecomposes to leucoflavin. No free radicals are formed in the absence of oxygen, but traces of oxygen allow for leucoflavin to reoxidize with free-radical generation. The catalysts, TEMED or DMAPN, are commonly added to speed up the free radical formation. Free radicals will cause acrylamide and bis-acrylamide to polymerize to form a gel matrix which can be used for sieving macromolecules. FMN is commonly used in the stacking gel for non-denaturing PAGE because native proteins can be sensitive to persulfate ions from ammonium persulfate. Another advantage of FMN over ammonium persulfate is that it will not start polymerizing until the gel is illuminated.
