Comments 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, 5-(carboxyamino)imidazole ribonucleotide synthase and EC?5.4.99.18, 5-(carboxyamino)imidazole ribonucleotide mutase [3]. 5-Carboxyamino-1-(5-phospho-D-ribosyl)imidazole is not a substrate.
Cofactor
History
