Identification
Name: Phosphoribosylaminoimidazole carboxylase catalytic subunit
Synonyms:
  • AIR carboxylase
  • AIRC
Gene Name: purE
Enzyme Class:
Biological Properties
General Function: Involved in 5-(carboxyamino)imidazole ribonucleotide mutase activity
Specific Function: This subunit can alone transform AIR to CAIR, but in association with purK, which possesses an ATPase activity, an enzyme complex is produced which is capable of converting AIR to CAIR efficiently under physiological condition
