molecular function |
| GO:0018537 | | coenzyme F420-dependent N5,N10-methenyltetrahydromethanopterin reductase activity | | Catalysis of the reaction: 5-methyltetrahydromethanopterin + coenzyme F420 + H(+) = 5,10-methylenetetrahydromethanopterin + 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. |
| GO:0016705 | | oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen | | Catalysis of an oxidation-reduction (redox) reaction in which hydrogen or electrons are transferred from each of two donors, and molecular oxygen is reduced or incorporated into a donor. |
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. |
cellular component |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
