Function
function
Catalyzes the phosphorylation of riboflavin (vitamin B2) to form flavin mononucleotide (FMN) coenzyme.
Catalytic activity
- ATP + riboflavin = ADP + FMN + H+
Cofactor
Note: Binds 1 zinc ion per subunit.
Pathway
Cofactor biosynthesis; FMN biosynthesis; FMN from riboflavin (ATP route): step 1/1.
