Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the transfer of the AMP portion of ATP to flavin mononucleotide (FMN) to produce flavin adenine dinucleotide (FAD) coenzyme.UniRule annotation

Catalytic activityi

ATP + FMN = diphosphate + FAD.UniRule annotation

Cofactori

a divalent metal cationUniRule annotation

Pathwayi: FAD biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes FAD from FMN.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. FAD synthase (ribL)
This subpathway is part of the pathway FAD 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 FAD from FMN, the pathway FAD biosynthesis and in Cofactor biosynthesis.

Similar proteinsi

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 one 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.
