Protein attributes

Sequence length	189 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Catalyzes the phosphorylation of riboflavin (vitamin B2) to form flavin mononucleotide (FMN) coenzyme By similarity.
Catalytic activity	ATP + riboflavin = ADP + FMN.
Cofactor	Zinc or magnesium By similarity.
Pathway	Cofactor biosynthesis; FMN biosynthesis; FMN from riboflavin (ATP route): step 1/1.
Sequence similarities	Belongs to the flavokinase family.
Sequence caution	The sequence CAG61658.1 differs from that shown. Reason: Erroneous initiation.
