Trifunctional purine biosynthetic protein adenosine-3


Trifunctional purine biosynthetic protein adenosine-3 is an enzyme that in humans is encoded by the GART gene.
This protein is a trifunctional polypeptide. It has Phosphoribosylamine—glycine ligase, Phosphoribosylglycinamide formyltransferase, AIR synthetase activity which is required for de novo purine biosynthesis.
