| GO:0003824 | catalytic activity | Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic. |
| GO:0003674 | molecular_function | Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions. |
| GO:0009975 | cyclase activity | Catalysis of a ring closure reaction. |
| GO:0009976 | tocopherol cyclase activity | Catalysis of the reaction: alkene group + alcohol group on same molecule = cyclic ether. Substrates are 2-methyl-6-phytyl-1,4- hydroquinone (forms delta-tocopherol) and 2,3-dimethyl-5-phytyl-1,4-hydroquinone (forms gamma-tocopherol). |
