Gene

fmn1

Organism
Aspergillus oryzae (strain ATCC 42149 / RIB 40) (Yellow koji mold)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-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

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.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
