Protein

Bifunctional riboflavin kinase/FMN adenylyltransferase

Gene

ribF

Organism
Pseudomonas fluorescens
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
