(NH4)2SO4 | inhibitory effect on NADPH-dependent 3-phosphohydroxypyruvate reduction | Sulfurisphaera tokodaii | |
3-phosphohydroxypyruvate | product inhibition of 3-phospho-D-glycerate oxidation, variable substrate: 3-phospho-D-glycerate, inhibition pattern: competitive; product inhibition of 3-phospho-D-glycerate oxidation, variable substrate: NAD, inhibition pattern: non-competitive | Sulfurisphaera tokodaii | |
ADP | weak inhibitory effect on 3-phospho-D-glycerate oxidation, remaining activity: 86% | Sulfurisphaera tokodaii | |
AMP | weak inhibitory effect on 3-phospho-D-glycerate oxidation, remaining activity: 75% | Sulfurisphaera tokodaii | |
ATP | weak inhibitory effect on 3-phospho-D-glycerate oxidation, remaining activity: 85% | Sulfurisphaera tokodaii | |
K2HPO4 | inhibitory effect on NADPH-dependent 3-phosphohydroxypyruvate reduction. It appears that the phosphate ion PO43- exerts its inhibitory effect by binding to the free enzyme and NADPH-enzyme complex | Sulfurisphaera tokodaii | |
additional information | unlike the Escherichia coli PGDH no inhibition by L-serine | Sulfurisphaera tokodaii | |
NADH | product inhibition of 3-phospho-D-glycerate oxidation, variable substrate: 3-phospho-D-glycerate, inhibition pattern: non-competitive; product inhibition of 3-phospho-D-glycerate oxidation, variable substrate: NAD, inhibition pattern: competitive | Sulfurisphaera tokodaii | |
