4.2.99.21 | additional information | the 2H kinetic isotope effects on kcat and the ratio kcat/Km are 2.34 and 1.75, respectively. Chemistry is significantly rate-determining for the enzyme. The magnitude of the isotope effect is consistent with considerable C-H bond cleavage in the transition state. The significant 2H kinetic isotope effect and quantitative transfer of the label to pyruvate are both consistent with a pericyclic reaction mechanism | Pseudomonas aeruginosa | ? | - |
