WebbAbstract. Thousands of new metabolic and regulatory enzymes have evolved by gene duplication and divergence since the dawn of life. New enzyme activities often originate from promiscuous secondary activities that have become important for fitness due to a change in the environment or a mutation. Mutations that make a promiscuous activity ... WebbCoenzyme F. 420. Coenzyme F420 or 8-hydroxy-5-deazaflavin is a coenzyme (sometimes called a cofactor) involved in redox reactions in methanogens, [1] in many Actinomycetota, and sporadically in other bacterial lineages. It is a flavin derivative. The coenzyme is a substrate for coenzyme F 420 hydrogenase, [2] 5,10 ... forced damped oscillation
