Glossary: coenzyme F420 = N-(N-{O-[5-(8-hydroxy-2,4-dioxo-2,3,4,10-tetrahydropyrimido[4,5-b]quinolin-10-yl)-5-deoxy-L-ribityl-1-phospho]-(S)-lactyl}-γ-L-glutamyl)-L-glutamate
Other name(s): 8-hydroxy-5-deazaflavin-reducing hydrogenase; F420-reducing hydrogenase; coenzyme F420-dependent hydrogenase
Systematic name: hydrogen:coenzyme F420 oxidoreductase
Comments: An iron-sulfur flavoprotein (FAD) containing nickel. The enzyme from some sources contains selenocysteine. The enzyme also reduces the riboflavin analogue of F420, flavins and methylviologen, but to a lesser extent. The hydrogen acceptor coenzyme F420 is a deazaflavin derivative.
