FunFam 6: Probable multifunctional protein ADE2

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Phosphoribosylaminoimidazole carboxylase. [EC: 4.1.1.21]
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.

Phosphoribosylaminoimidazolesuccinocarboxamide synthase. [EC: 6.3.2.6]
ATP + 5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxylate + L-aspartate = ADP + phosphate + (S)-2-(5-amino-1-(5-phospho-D- ribosyl)imidazole-4-carboxamido)succinate.
  • Forms part of the purine biosynthesis pathway.
