Trifunctional purine biosynthetic protein adenosine-3 is an enzyme that in humans is encoded by the GART gene.^[1]

This protein is a trifunctional polypeptide. It has phosphoribosylglycinamide formyltransferase (EC 6.3.4.13), phosphoribosylglycinamide synthetase (EC 6.3.3.1), phosphoribosylaminoimidazole synthetase (EC 2.1.2.2) activity which is required for de novo purine biosynthesis.
