Protein

Biotin synthase

Gene

bioB

Organism
Burkholderia ambifaria (strain MC40-6)
Status
Reviewed-Annotation score: -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 + 2 reduced [2Fe-2S] ferredoxin = biotin + (sulfur carrier) + 2 L-methionine + 2 5'-deoxyadenosine + 2 oxidized [2Fe-2S] ferredoxin.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

Pathwayi: biotin biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes biotin from 7,8-diaminononanoate.UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. ATP-dependent dethiobiotin synthetase BioD (bioD)
  2. Biotin synthase (bioB)
This subpathway is part of the pathway biotin biosynthesis, which is itself part of Cofactor biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes biotin from 7,8-diaminononanoate, the pathway biotin biosynthesis and in Cofactor biosynthesis.
