Michaelis constant formula
Webb21 mars 2024 · In addition to the Michaelis Menten constant (K m) and the maximal conversion rate (v max) values , inhibition constants (K ic, K iu) were calculated by fitting the data by two approaches: (i) According to the mixed inhibition equation (Equation (4)) or competitive inhibition equation (Equation (5)), applying an optimal global fit … WebbThe Michaelis constant K m is equal to the reactant concentration at which r A =v max /2. What is the SI unit of enzyme activity? Enzyme activity The SI unit is the katal, 1 katal = 1 mol s 1, but this is an excessively large unit. A more practical and commonly used value is enzyme unit (U) = 1 mol min 1. What is the unit of k cat?
