Protein

Riboflavin synthase

Gene

ribE

Organism
Actinobacillus pleuropneumoniae (Haemophilus pleuropneumoniae)
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
