Comments [?]

Function Catalyzes the radical-mediated synthesis of 5-amino-5-(4-hydroxybenzyl)-6-(D-ribitylimino)-5,6-dihydrouracil from 5-amino-6-(D-ribitylamino)uracil and L-tyrosine.
Catalytic activity RHEA:55200: 5-amino-6-(D-ribitylamino)uracil + L-tyrosine + S-adenosyl-L-methionine = 2-iminoacetate + 5'-deoxyadenosine + 5-amino-5-(4-hydroxybenzyl)-6-(D-ribitylimino)-5,6-dihydrouracil + H(+) + L-methionine
EC 2.5.1.147
case <FTGroup:1>
Cofactor [4Fe-4S] cluster
Note: Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine.
end case
Pathway Cofactor biosynthesis; coenzyme F0 biosynthesis.
Subunit The FO synthase complex consists of two subunits, CofG and CofH.
Similarity Belongs to the radical SAM superfamily. CofH 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.
