Using \(\beta\)-galactosidase as an enzyme model, the students assess the effect of the substrate o-nitrophenyl-\(\beta\)-D-galactopynaroside (ONPG) on the initial rate (doi: 10.1002/bmb.21522).The data … Webb1 tlnSo St = − 1 Km(So − St) t + Vmax Km. Equation (3) can be recognized as the equation of a line where the dependent variable is 1 tlnSo St and the independent variable is ( So − St) t. Thus, if the data given in the table above are conveniently transformed, they can be fit to a line by least square.
Webb15 maj 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.
