Enzyme Information

5.4.99.18
5-(carboxyamino)imidazole ribonucleotide mutase.
based on mapping to UniProt P9WHM1
5-carboxyamino-1-(5-phospho-D-ribosyl)imidazole = 5-amino-1-(5-phospho-D- ribosyl)imidazole-4-carboxylate.
-!- In eubacteria, fungi and plants, this enzyme, along with EC 6.3.4.18, is required to carry out the single reaction catalyzed by EC 4.1.1.21 in vertebrates. -!- In the absence of EC 6.3.2.6, the reaction is reversible. -!- The substrate is readily converted into 5-amino-1-(5-phospho-D- ribosyl)imidazole by non-enzymic decarboxylation.
