Protein existenceInferred from homology

General annotation (Comments)

Function

Catalyzes the conversion of dethiobiotin (DTB) to biotin by the insertion of a sulfur atom into dethiobiotin via a radical-based mechanism By similarity. HAMAP-Rule MF_01694

Catalytic activity

Dethiobiotin + sulfur-(sulfur carrier) + 2 S-adenosyl-L-methionine = biotin + (sulfur carrier) + 2 L-methionine + 2 5'-deoxyadenosine. HAMAP-Rule MF_01694

Cofactor

Binds 1 4Fe-4S cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine By similarity.

Binds 1 2Fe-2S cluster. The cluster is coordinated with 3 cysteines and 1 arginine By similarity.

Pathway

Cofactor biosynthesis; biotin biosynthesis; biotin from 7,8-diaminononanoate: step 2/2. HAMAP-Rule MF_01694

Subunit structure

Homodimer By similarity. HAMAP-Rule MF_01694

Sequence similarities

Belongs to the radical SAM superfamily. Biotin synthase family.
