FUNCTIONCatalyzes the radical-mediated synthesis of 7,8-didemethyl-8- hydroxy-5-deazariboflavin (FO) from 5-amino-5-(4-hydroxybenzyl)-6-(D- ribitylimino)-5,6-dihydrouracil.
CATALYTIC ACTIVITY Reaction=5-amino-5-(4-hydroxybenzyl)-6-(D-ribitylimino)-5,6- dihydrouracil + S-adenosyl-L-methionine = 5'-deoxyadenosine + 7,8- didemethyl-8-hydroxy-5-deazariboflavin + H(+) + L-methionine + NH4(+); Xref=Rhea:RHEA:55204, ChEBI:CHEBI:15378, ChEBI:CHEBI:17319, ChEBI:CHEBI:28938, ChEBI:CHEBI:57844, ChEBI:CHEBI:59789, ChEBI:CHEBI:59904, ChEBI:CHEBI:85936; EC=4.3.1.32;
case <FTGroup:1>
COFACTOR Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Note=Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine.;
end case
PATHWAYCofactor biosynthesis; coenzyme F0 biosynthesis.
SUBUNITThe FO synthase complex consists of two subunits, CofG and CofH.
SIMILARITYBelongs to the radical SAM superfamily. CofG family.

Comments Euryarchaeota, cyanobacteria and actinomycetes are known to produce coenzyme FO. Euryarchaeota and actinomycetes use it to synthesize coenzyme F420, whereas cyanobacteria use it for FO-dependent DNA photolyases. In actinomycetes, the two subunits cofG and cofH are fused, and are called fbiC. Possible wrong starts.
