Enzyme Information

6.3.4.18
5-(carboxyamino)imidazole ribonucleotide synthase.
based on mapping to UniProt A0A0H3KFM7
ATP + 5-amino-1-(5-phospho-D-ribosyl)imidazole + HCO(3)(-) = ADP + phosphate + 5-carboxyamino-1-(5-phospho-D-ribosyl)imidazole.
-!- In Escherichia coli, this enzyme, along with EC 5.4.99.18, is required to carry out the single reaction catalyzed by EC 4.1.1.21 in vertebrates. -!- Carboxyphosphate is the putative acyl phosphate intermediate. -!- Involved in the late stages of purine biosynthesis.
