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]-
