    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
