Methanogenesis in archaea: Biochemistry, coenzymes (F₄₂₀ coenzyme M) and regulation
1) Methanogenesis
- Methanogenesis is a unique anaerobic respiratory process that produces methane as its metabolic product.
- Methanogens are strictly anaerobic archaea capable of producing methane.
Key features:
- Strictly anaerobic.
- Final step in anaerobic decomposition.
- Uses unusual coenzymes such as Coenzyme F₄₂₀, Coenzyme M, Methanofuran and H₄MPT.
- Low energy yield.
- Produces ATP via H+ or Na+ gradients.
Unique to Archaea and contribute to the global methane cycle.
