Protein

Biotin synthase

Gene

bioB

Organism
Erwinia tasmaniensis (strain DSM 17950 / Et1/99)
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

Protein has several cofactor binding sites:
  • [4Fe-4S] clusterUniRule annotationNote: Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine.UniRule annotation
  • [2Fe-2S] clusterUniRule annotationNote: Binds 1 [2Fe-2S] cluster. The cluster is coordinated with 3 cysteines and 1 arginine.UniRule annotation
