molecular function
    GO:0008901    ferredoxin hydrogenase activity    Catalysis of the reaction: 2 reduced ferredoxin + 2 H+ = 2 oxidized ferredoxin + H2.
    GO:0030268    methylenetetrahydromethanopterin dehydrogenase activity    Catalysis of the reaction: 5,10-methylenetetrahydromethanopterin + coenzyme F420 + 2 H(+) = 5,10-methenyl-5,6,7,8-tetrahydromethanopterin + reduced coenzyme F420.
    GO:0016491    oxidoreductase activity    Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
biological process
    GO:0015948    methanogenesis    The chemical reactions and pathways resulting in the formation of methane, a colorless, odorless, flammable gas with the formula CH4. It is the simplest of the alkanes.
    GO:0019386    methanogenesis, from carbon dioxide    The chemical reactions and pathways resulting in the formation of methane, a colorless, odorless, flammable gas with the formula CH4, from other compounds, including carbon dioxide (CO2).
    GO:0006730    one-carbon metabolic process    The chemical reactions and pathways involving the transfer of one-carbon units in various oxidation states.
    GO:0055114    oxidation-reduction process    A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
