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 enzyme catalyzes ...	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

The N-terminal domain of AIR synthase forms the dimer interface of the protein, and is suggested as a putative ATP binding domain [1].	Domain
