Enzyme reactions

• Enzyme class: E.C.5.4.99.18 - 5-(carboxyamino)imidazole ribonucleotide mutase.
• Reaction: 5-carboxyamino-1-(5-phospho-D-ribosyl)imidazole + H⁺ = 5-amino-1- (5-phospho-D-ribosyl)imidazole-4-carboxylate

5-carboxyamino-1-(5-phospho-D-ribosyl)imidazole (Bound ligand (Het Group name = AIR) matches with 86.36% similarity) + H(+) = 5-amino-1- (5-phospho-D-ribosyl)imidazole-4-carboxylate
