Protein

Biotin synthase

Gene

bioB

Organism
Escherichia coli O157:H7 (strain EC4115 / EHEC)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Catalyzes the conversion of dethiobiotin (DTB) to biotin by the insertion of a sulfur atom into dethiobiotin via a radical-based mechanism.UniRule annotation

Catalytic activityi

Dethiobiotin + sulfur-(sulfur carrier) + 2 S-adenosyl-L-methionine = biotin + (sulfur carrier) + 2 L-methionine + 2 5'-deoxyadenosine.UniRule annotation

Cofactori

Binds 1 4Fe-4S cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine.UniRule annotation
Binds 1 2Fe-2S cluster. The cluster is coordinated with 3 cysteines and 1 arginine.UniRule annotation
