| | GO:0070626 | | (S)-2-(5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamido)succinate AMP-lyase (fumarate-forming) activity | | Catalysis of the reaction: (S)-2-(5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamido)succinate = fumarate + 5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide. |
| | GO:0004018 | | N6-(1,2-dicarboxyethyl)AMP AMP-lyase (fumarate-forming) activity | | Catalysis of the reaction: N6-(1,2-dicarboxyethyl)AMP = fumarate + AMP. |
| | 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:0044208 | | 'de novo' AMP biosynthetic process | | The chemical reactions and pathways resulting in the formation of adenosine monophosphate (AMP) from inosine 5'-monophosphate (IMP). |
| | GO:0006189 | | 'de novo' IMP biosynthetic process | | The chemical reactions and pathways resulting in the formation of IMP, inosine monophosphate, by the stepwise assembly of a purine ring on ribose 5-phosphate. |
| | GO:0006167 | | AMP biosynthetic process | | The chemical reactions and pathways resulting in the formation of AMP, adenosine monophosphate. |
| | GO:0051262 | | protein tetramerization | | The formation of a protein tetramer, a macromolecular structure consisting of four noncovalently associated identical or nonidentical subunits. |
| | GO:0006164 | | purine nucleotide biosynthetic process | | The chemical reactions and pathways resulting in the formation of a purine nucleotide, a compound consisting of nucleoside (a purine base linked to a deoxyribose or ribose sugar) esterified with a phosphate group at either the 3' or 5'-hydroxyl group of the sugar. |
| | GO:0009152 | | purine ribonucleotide biosynthetic process | | The chemical reactions and pathways resulting in the formation of a purine ribonucleotide, a compound consisting of ribonucleoside (a purine base linked to a ribose sugar) esterified with a phosphate group at either the 3' or 5'-hydroxyl group of the sugar. |
