Protein

Putative bifunctional riboflavin kinase/FMN adenylyltransferase

Gene

ribF

Organism
Geobacillus thermodenitrificans (strain NG80-2)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the phosphorylation of riboflavin to FMN followed by the adenylation of FMN to FAD.1 Publication

Caution

This sequence is divergent compared to other bacterial RibF.Curated

Catalytic activityi

ATP + riboflavin = ADP + FMN.1 Publication
ATP + FMN = diphosphate + FAD.1 Publication

Kineticsi

    1. Vmax=270.3 µmol/min/mg enzyme toward FMN1 Publication
    2. Vmax=170.09 µmol/min/mg enzyme toward riboflavin1 Publication

    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. Putative bifunctional riboflavin kinase/FMN adenylyltransferase (ribF), Riboflavin biosynthesis protein (GTNG_1121)
    This subpathway is part of the pathway FAD biosynthesis, which is itself part of Cofactor biosynthesis.
