| GO:0003674 | molecular_function | A molecular process that can be carried out by the action of a single macromolecular machine, usually via direct physical interactions with other molecular entities. Function in this sense denotes an action, or activity, that a gene product (or a complex) performs. |
| 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:0016829 | lyase activity | Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring. |
| GO:0016840 | carbon-nitrogen lyase activity | Catalysis of the release of ammonia or one of its derivatives, with the formation of a double bond or ring. Enzymes with this activity may catalyze the actual elimination of the ammonia, amine or amide, e.g. CH-CH(-NH-R) = C=CH- + NH2-R. Others, however, catalyze elimination of another component, e.g. water, which is followed by spontaneous reactions that lead to breakage of the C-N bond, e.g. L-serine ammonia-lyase (EC:4.3.1.17), so that the overall reaction is C(-OH)-CH(-NH2) = CH2-CO- + NH3, i.e. an elimination with rearrangement. The sub-subclasses of EC:4.3 are the ammonia-lyases (EC:4.3.1), lyases acting on amides, amidines, etc. (EC:4.3.2), the amine-lyases (EC:4.3.3), and other carbon-nitrogen lyases (EC:4.3.99). |
