Reaction: RFK:Mg2+ phosphorylates RIB
- in pathway: Vitamin B2 (riboflavin) metabolism
Phosphorylation of riboflavin (RIB) results in the formation of the first cofactor, flavin mononucleotide (FMN). This reaction is catalyzed by riboflavin kinase (RFK), a cytosolic enzyme existing as a monomer. It utilizes either zinc or magnesium ions in the reaction.
