This is the N-terminal domain found in Formylglycinamide ribonucleotide amidotransferase (FGAR-AT), also known as Phosphoribosylformylglycinamidine synthase (EC:6.3.5.3), PurL and formylglycinamidine ribonucleotide (FGAM) synthase. This enzyme catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide and glutamine to formylglycinamidine ribonucleotide, ADP, Pi, and glutamate in the fourth step of the purine biosynthetic pathway [3].

This family includes Hydrogen expression/formation protein HypE Swiss:P24193, AIR synthases Swiss:P08178 EC:6.3.3.1, FGAM synthase Swiss:P35852 EC:6.3.5.3 and selenide, water dikinase Swiss:P16456 EC:2.7.9.3. The function of the C-terminal domain of AIR synthase is unclear, but the cleft formed between N and C domains is postulated as a sulphate binding site [1].	Domain

This is the linker domain found in Formylglycinamide ribonucleotide amidotransferase (FGAR-AT), also known as Phosphoribosylformylglycinamidine synthase (EC:6.3.5.3), PurL and formylglycinamidine ribonucleotide (FGAM) synthase. This enzyme catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to formylglycinamidine ribonucleotide (FGAM), ADP, Pi, and glutamate in the fourth step of the purine biosynthetic pathway. The structure analysis of Salmonella typhimurium FGAR-AT reveals that this linker domain is made up of a long hydrophilic belt with an extended conformation [4].	Domain

This entry represents the PurM_N-like domain of formylglycinamide ribonucleotide amidotransferase (FGAR-AT) and related proteins. FGAR-AT catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) to formylglycinamidine ribonucleotide (FGAM) in the fourth step of the purine biosynthetic pathway. This domain consists of an antiparallel beta-sheet with two helices packed on one side [1-5].	Domain
