Enzyme Information

4.1.1.21
Phosphoribosylaminoimidazole carboxylase.
based on mapping to UniProt Q73PV9
5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxylate = 5-amino-1- (5-phospho-D-ribosyl)imidazole + CO(2).
-!- While this is the reaction that occurs in vertebrates during purine biosynthesis, two enzymes are required to carry out the same reaction in Escherichia coli, namely EC 6.3.4.18 and EC 5.4.99.18. -!- 5-carboxyamino-1-(5-phospho-D-ribosyl)imidazole is not a substrate.
