7,8-didemethyl-8-hydroxy-5-deazariboflavin synthase

Binds a [4Fe-4S] cluster. The cluster is coordinated by 3 cysteines and an exchangeable AdoMet molecule. The first stage of catalysis is reduction of the 2 AdoMet to produce 2 methionine and 2 5'-deoxyadenosin-5-yl radicals that extract a hydrogen from each of the substrates permitting the condensation of the two. The overall reaction catalysed is the transfer of the hydroxybenzyl group from 4-hydroxyphenylpyruvate (HPP) to 5-amino-6-ribitylaminopyrimidine-2,4(1H,3H)-dione to form 7,8-didemethyl-8-hydroxy-5-deazariboflavin (FO). 7,8-Didemethyl-8-hydroxy-5-deazariboflavin is the chromophore of the hydride carrier coenzyme F420.
