Catalytic efficiency and kcat/KM: a useful comparator?

Web17 de fev. de 2024 · At initial reaction time, when t ≈ 0, little product formation occurs, therefore the backward reaction rate of k-2 may be neglected. The new reaction becomes: E + S ↔ ES → E + P Assuming steady state, the following rate equations may be written as: Rate of formation of ES = k 1 [E][S] Rate of breakdown of ES = (k-1 + k 2) [ES] Web19 de abr. de 2024 · The Michaelis-Menten constant K M has a rigorous definition based on rate constants, and its dimensions are the same as those of a concentration. If you interpret K M as the affinitiy of the enzyme to the substrate, you have to know that higher values of K M correspond to lower degree of binding.

WebThe maximal velocity of the reaction (or maximal rate) Vmax is the rate attained when the enzyme sites are saturated with substrate, i.e. when the substrate concentration is much higher than the KM. Examples: Q8W1X2, Q9V2Z6 The Vmax value depends on environmental conditions, such as pH, temperature and ionic strength. Web19 de abr. de 2024 · The key difference between Km and Vmax is that Km measures how easily an enzyme can be saturated by the substrate, whereas Vmax is the maximum rate at which an enzyme is catalyzed when the enzyme is saturated by the substrate..
