RC STRAIN=ATCC BAA-835; RX PubMed=21390229; DOI=10.1371/journal.pone.0016876; RA van Passel M.W., Kant R., Zoetendal E.G., Plugge C.M., Derrien M., RA Malfatti S.A., Chain P.S., Woyke T., Palva A., de Vos W.M., Smidt H.; RT "The genome of Akkermansia muciniphila, a dedicated intestinal mucin RT degrader, and its use in exploring intestinal metagenomes."; RL PLoS ONE 6:E16876-E16876(2011). CC -!- FUNCTION: Catalyzes the conversion of dethiobiotin (DTB) to biotin CC by the insertion of a sulfur atom into dethiobiotin via a radical- CC based mechanism. {ECO:0000255|HAMAP-Rule:MF_01694}. CC -!- CATALYTIC ACTIVITY: Dethiobiotin + sulfur-(sulfur carrier) + 2 S- CC adenosyl-L-methionine = biotin + (sulfur carrier) + 2 L-methionine CC + 2 5'-deoxyadenosine. {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:49601; 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 CC 7,8-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 CC synthase family. {ECO:0000255|HAMAP-Rule:MF_01694}.
