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:0000256|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 Note=Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3
CC cysteines and an exchangeable S-adenosyl-L-methionine.
CC {ECO:0000256|HAMAP-Rule:MF_01694};
CC -!- PATHWAY: Cofactor biosynthesis; biotin biosynthesis; biotin from 7,8-
CC diaminononanoate: step 2/2. {ECO:0000256|ARBA:ARBA00004942,
