Protein

Trifunctional protein RibF/MnmA

Gene

ribF/mnmA

Organism
Mycoplasma gallisepticum (strain R(low / passage 15 / clone 2))
Status
Reviewed - Annotation score: 5 out of 5- Protein inferred from homologyi

Functioni

Involved in FAD and FMN biosynthesis.By similarity
Catalyzes the 2-thiolation of uridine at the wobble position (U34) of tRNA, leading to the formation of s2U34.By similarity

Catalytic activityi

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