Nettet13. mar. 2024 · In addition to this, the double-reciprocal line can be used to differentiate between the three different types of reversible inhibitors. Since competitive inhibitors do not change the Vmax but increase the Km, the double-reciprocal line will increase its slope and change its x-intercept but keeps the y-intercept unchanged. NettetWhen used for determining the type of enzyme inhibition, the Lineweaver-Burk plot can distinguish competitive, noncompetitive and uncompetitive inhibitors. Competitive inhibitors have the same y-intercept as uninhibited enzyme (since V max is unaffected by competitive inhibitors the inverse of Vmax also doesn't change) but there are different …

Nettet16. aug. 2024 · This is called noncompetiive inhibition. It is quite rare as it would be difficult to imagine a large inhibitor which inhibits the turnover of bound substrate having no effect on binding of S to E. However covalent interaction of protons with both E and ES can lead to noncompetitive inhibition.
