Protein Family Models

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]. [1]. 10508786. X-ray crystal structure of aminoimidazole ribonucleotide synthetase (PurM), from the Escherichia coli purine biosynthetic pathway at 2.5 A resolution. Li C, Kappock TJ, Stubbe J, Weaver TM, Ealick SE;. Structure Fold Des 1999;7:1155-1166. (from Pfam)

The N-terminal domain of AIR synthase forms the dimer interface of the protein, and is suggested as a putative ATP binding domain [1]. [1]. 10508786.

phosphoribosylformylglycinamidine cyclo-ligase catalyzes the conversion of formylglycinamide ribonucleotide (FGAM) and ATP to AIR, ADP, and Pi, in the fifth step in de novo purine biosynthesis
