Description
Function: phosphoribosylaminoimidazole carboxylase catalytic subunit
This carboxylase is an enzyme involved in nucleotide biosynthesis, particularly in purine biosynthesis. It catalyzes the conversion of AIR (5???-phosphoribosyl-5-aminoimidazole) into CAIR (5???-phosphoribosyl-4-carboxy-5-aminoimidazole).
5-aminoimidazole ribonucleotide + CO2 5'-phosphoribosyl-4-carboxy-5-aminoimidazole + 2 H+
AIR synthetase is the fifth enzyme in the de novo synthesis of purine nucleotides. It catalyzes the reaction to form 5-aminoimidizole ribonucleotide (AIR) from formylglycinamidine-ribonucleotide FGAM. This reaction closes the ring and produces a 5-membered imidazole ring of the purine nucleus (AIR):
