Trifunctional purine biosynthetic protein adenosine-3

Trifunctional purine biosynthetic protein adenosine-3 is an is_associated_with::enzyme that in humans is encoded by the GART is_associated_with::gene.

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