Structure of Coenzyme F420
Coenzyme F420 or 8-hydroxy-5-deazaflavin is a coenzyme involved in redox reactions in methanogens,[1] in many Actinobacteria, and sporadically in other bacterial lineages. It is a flavin derivative. The coenzyme is a substrate for coenzyme F420 hydrogenase,[2] 5,10-methylenetetrahydromethanopterin reductase and methylenetetrahydromethanopterin dehydrogenase.[3][4]
A particularly rich natural source of F420 is Mycobacterium smegmatis, in which several dozen enzymes use F420 instead of the related cofactor FMN used by homologous enzymes in most other species.[5]
