Literature summary for 2.4.2.17 extracted from
- Synergistic inhibition of ATP phosphoribosyltransferase by guanosine tetraphosphate and histidine (1977), Biochem. Biophys. Res. Commun., 74, 172-177.
Inhibitors
| Inhibitors | Comment | Organism | Structure |
|---|---|---|---|
| Guanosine 5'-diphosphate-3'-diphosphate | in presence of partially inhibiting concentrations of histidine guanosine 5'-diphosphate-3'-diphosphate becomes a potent inhibitor of the residual activity of ATP phosphoribosyltransferase, no inhibition in absence of histidine, inhibition is slowly reversible | Salmonella enterica subsp. enterica serovar Typhimurium |  |
| L-histidine | feed-back inhibition | Salmonella enterica subsp. enterica serovar Typhimurium | |
