wild type in its apo-state and mutants D7N and D7N/D176A in complex with two different conformations of the labile substrate N'-[(5'-phosphoribosyl)formimino]-5-aminoimidazole-4-carboxamide ribonucleotide, i.e. ProFAR. Residue D7 acts as the catalytic base, and D176 acts as the catalytic acid | Salmonella enterica subsp. enterica serovar Typhimurium |

physiological function | catalytic mechanism involves long loops on the catayltic face that enclose the substrate. Substrate ProFAR adopts an extended conformation where its non-reacting half is in a product-like conformation. This change is associated with shifts in a hydrogen bond network including residues His47, Asp129, Thr171, and Ser202 | Salmonella enterica subsp. enterica serovar Typhimurium |
