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       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};
