Abstract Methanosphaera stadtmanae, a member of the Methanobacteriales reduces methanol, but not CO2 with H2 or 2-propanol to produce methane. In cell-free extracts of M. stadtmanae the activities of several enzymes involved in electron transfer were measured. The activities of an F420-nonreactive hydrogenase, NADP+: F420 oxidoreductase, NADP+-dependent 2-propanol dehydrogenase, and a methyl viologen dependent F420 dehydrogenase were observed. Based on the presence of these particular enzyme activities, their cofactor requirements and the absence of F420-dependent hydrogenase activity, a model of the electron transport pathway through the coenzyme F420 to provide electrons for biosynthesis, was formulated.
