CC -!- FUNCTION: Catalyzes the conversion of dethiobiotin (DTB) to biotin by
CC the insertion of a sulfur atom into dethiobiotin via a radical-based
CC mechanism. {ECO:0000255|HAMAP-Rule:MF_01694}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(4R,5S)-dethiobiotin + [sulfur carrier]-SH + 2 reduced [2Fe-
CC 2S]-[ferredoxin] + 2 S-adenosyl-L-methionine = 2 5'-deoxyadenosine +
CC [sulfur carrier]-H + biotin + 2 L-methionine + 2 oxidized [2Fe-2S]-
CC [ferredoxin]; Xref=Rhea:RHEA:22060, Rhea:RHEA-COMP:10000, Rhea:RHEA-
CC COMP:10001, Rhea:RHEA-COMP:14737, Rhea:RHEA-COMP:14739,

CC ChEBI:CHEBI:59789, ChEBI:CHEBI:64428, ChEBI:CHEBI:149473; EC=2.8.1.6;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01694};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01694};
CC Note=Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3
CC cysteines and an exchangeable S-adenosyl-L-methionine.
CC {ECO:0000255|HAMAP-Rule:MF_01694};
CC -!- COFACTOR:
CC Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01694};
CC Note=Binds 1 [2Fe-2S] cluster. The cluster is coordinated with 3
CC cysteines and 1 arginine. {ECO:0000255|HAMAP-Rule:MF_01694};
CC -!- PATHWAY: Cofactor biosynthesis; biotin biosynthesis; biotin from 7,8-
CC diaminononanoate: step 2/2. {ECO:0000255|HAMAP-Rule:MF_01694}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01694}.
CC -!- SIMILARITY: Belongs to the radical SAM superfamily. Biotin synthase
CC family. {ECO:0000255|HAMAP-Rule:MF_01694}.
