CC -!- FUNCTION: Catalyzes the phosphorylation of riboflavin (vitamin B2) to
CC form flavin mononucleotide (FMN) coenzyme.
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;
CC Note=Binds 1 zinc ion per subunit.;
CC -!- PATHWAY: Cofactor biosynthesis; FMN biosynthesis; FMN from riboflavin
CC (ATP route): step 1/1.
CC -!- SUBUNIT: Monomer.
CC -!- SIMILARITY: Belongs to the flavokinase family. {ECO:0000305}.
