Hydrogenotrophic methanogenesis in archaeal phylum Verstraetearchaeota reveals the shared ancestry of all methanogens
B. A. Berghuis, F. B. Yu, F. Schulz…·S. Quake
The paper discovers a hydrogenotrophic methanogenesis pathway in Verstraetearchaeota and the Wood-Ljungdahl pathway in Desulfurococcales, suggesting an ancient origin of hydrogenotrophic methanogenesis and a later adaptation to methylotrophic methanogenesis.
