Protein

Riboflavin synthase

Gene

ribE

Organism
Photobacterium leiognathi
Status
Reviewed - Annotation score: 2 out of 5- Protein inferred from homologyi

Functioni

Catalyzes the dismutation of two molecules of 6,7-dimethyl-8-ribityllumazine, resulting in the formation of riboflavin and 5-amino-6-(D-ribitylamino)uracil.By similarity

Catalytic activityi

2 6,7-dimethyl-8-(1-D-ribityl)lumazine = riboflavin + 4-(1-D-ribitylamino)-5-amino-2,6-dihydroxypyrimidine.
