The Lineweaver-Burk plot intersected above the x-axis [18,19,20], indicating that HTOR inhibited the reaction in a noncompetitive manner over the substrate range from 0.
To determine the kinetics parameters, Dixon plot was used to determine inhibition constant (Ki) [15] and Lineweaver-Burk plot [16] over the substrate was used at different concentrations 2.
The data were fitted to Michaelis-Menten model and further analyzed using Lineweaver-Burk plot and Dixon plot.
This was indicated by the comparable Michaelis constant (Km) values obtained from the Lineweaver-Burk plot (0.
Km and Vmax values for the enzyme at optimal pH and temperature were determined by Lineweaver-Burk plot [27].
