It catalyses the reaction of quinolinic acid with 5-phosphoribosyl-1-pyrophosphate (PRPP) in the presence of Mg2+ to give rise to nicotinic acid mononucleotide (NaMN), pyrophosphate and carbon dioxide [1,2]. The QA substrate is bound between the C-terminal domain of one subunit, and the N-terminal domain of the other. The N-terminal domain has an alpha/beta hammerhead fold.
