Protein

Bifunctional riboflavin kinase/FMN adenylyltransferase

Gene

ribF

Organism
Mycoplasma pneumoniae (strain ATCC 29342 / M129)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the phosphorylation of riboflavin to FMN followed by the adenylation of FMN to FAD.By similarity

Catalytic activityi

ATP + riboflavin = ADP + FMN.By similarity
ATP + FMN = diphosphate + FAD.By similarity

Pathwayi: FAD biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes FAD from FMN.By similarity
Proteins known to be involved in this subpathway in this organism are:
  1. Bifunctional riboflavin kinase/FMN adenylyltransferase (ribF)
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.

Pathwayi: FMN biosynthesis
