Chemistry of Coenzyme F420 in Environment

Abstract

Coenzyme F₄₂₀ is one of the ancient and rare coenzymes. The unique electrochemical properties of F₄₂₀ are compared with the ubiquitous flavin coenzymes FMN (flavin mononucleotide), FAD (flavin adenine dinucleotide), and nicotinamide coenzyme NADP+ (nicotinamide adenine dinucleotide phosphate). The 7,8-didemethyl-8-hydroxy-5-deazaflavin core of F₄₂₀ is structurally and biosynthetically related to FMN and FAD, but chemical reactions are similar to NADP+. The role of F₄₂₀ and related ancient coenzymes and cofactors in methanogenesis and methanotrophic reactions in methane and short alkane oxidations is widely increasing to understand the mechanism of global warming and climate change.
