Glycinamide ribonucleotide transformylase catalyses the third step in de novo purine biosynthesis, the transfer of a formyl group to 5'-phosphoribosylglycinamide. Formyltetrahydrofolate deformylase produces formate from formyl- tetrahydrofolate. Methionyl-tRNA formyltransferase transfers a formyl group onto the amino terminus of the acyl moiety of the methionyl aminoacyl-tRNA. Inclusion of the following members is supported by PSI-blast. HOXX_BRAJA (P31907) contains a related domain of unknown function. PRTH_PORGI (P46071) contains a related domain of unknown function. Y09P_MYCTU (Q50721) contains a related domain of unknown function.	Domain

Chains	Enzyme Name	Description	Catalytic Residues
A	glycinamide ribonucleotide transformylase M-CSA #363	Glycinamide ribonucleotide transformylase (GRT) catalyses the first two steps of purine biosynthesis: the transfer of formyl from 10-formyltetrahydrofolate to the amino group of glycinamide ribonucleotidem, forming glycinamide ribonucleotide and tetrahydrofolate. The enzyme’s role in DNA nucleotide biosynthesis makes it an interesting target for anti-neoplastic agents and for developing novel antifolate drugs to be used in cancer chemotherapy. Due to its biological and pharmacological significance, it has been the subject of intensive studies.
