NCI: Bifunctional purine biosynthesis protein PURH (592 aa, ~65 kDa) is encoded by the human ATIC gene. This protein plays a role in the mediation of purine biosynthesis.,MSH: An enzyme that catalyzes the conversion of aminoimidazole-4-carboxamide ribonucleotide to 5-formyl-aminoimidazole-4-carboxamide ribonucleotide in the purine de novo synthesis pathway. It requires the cofactor N(10)-FORMYLTETRAHYDROFOLATE as the formyl donor.
