CC   -!- FUNCTION: Catalyzes the phosphorylation of riboflavin (vitamin B2) to
CC       form flavin mononucleotide (FMN) coenzyme. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + riboflavin = ADP + FMN + H(+); Xref=Rhea:RHEA:14357,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:57986,
CC         ChEBI:CHEBI:58210, ChEBI:CHEBI:456216; EC=2.7.1.26;
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC       Note=Zinc or magnesium. {ECO:0000250};
CC   -!- PATHWAY: Cofactor biosynthesis; FMN biosynthesis; FMN from riboflavin
CC       (ATP route): step 1/1.
CC   -!- SIMILARITY: Belongs to the flavokinase family. {ECO:0000305}.
