Functioni

Catalyzes the phosphorylation of riboflavin (vitamin B2) to form flavin mononucleotide (FMN) coenzyme.By similarity

Catalytic activityi

ATP + riboflavin = ADP + FMN.

Cofactori

Zn2+By similarity, Mg2+By similarityNote: Zinc or magnesium.By similarity

Pathway:iFMN biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes FMN from riboflavin (ATP route).
Proteins known to be involved in this subpathway in this organism are:
  1. Riboflavin kinase (FMN1)
This subpathway is part of the pathway FMN biosynthesis, which is itself part of Cofactor biosynthesis.
