The michaelis-menten constant

WebMay 15, 2024 · The Michaelis-Menten constant ( Km ), the concentration of substrate ( [S]) providing half of enzyme maximal activity, is not the ( Kd ). In the simple E+S ⇄ ES → E+P or in more complex models describing S conversion into P, Km must be considered the constant defining the steady state at any substrate concentration.
