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
