Protein

Riboflavin kinase

Gene

fmn1

Organism
Aspergillus oryzae (strain ATCC 42149 / RIB 40) (Yellow koji mold)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

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

Pathwayi: FMN 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.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes FMN from riboflavin (ATP route), the pathway FMN biosynthesis and in Cofactor biosynthesis.
