The pathway of CO2 reduction to methane in Methanogenium tationis and Methanogenium thermophilicum is similar to that observed in other methanogens. In M. tationis a novel pterin, tatiopterin, is present. This pterin appears to be a structural and functional analog of methanopterin and sarcinapterin. Folate could not substitute for tatiopterin.
嗜热产甲烷菌和嗜温产甲烷菌中二氧化碳还原为甲烷的途径与其他产甲烷菌中观察到的相似。在嗜热产甲烷菌中存在一种新型蝶呤，即嗜热蝶呤。这种蝶呤似乎是甲烷蝶呤和肌动蛋白蝶呤的结构和功能类似物。叶酸不能替代嗜热蝶呤。
