WebA chart I memorized for the different types of inhibitors. Would just add that for uncompetitive, Km and Vmax decrease by exactly the same factor. That lets you distinguish between uncompetitive and a mixed inhibitor that decreases Km: the mixed one decreases Km by a different factor than Vmax. This is awesome. WebFor competitive and uncompetitive inhibitors when the assay conditions are [S] = Km, then Ki = I50/2. For different conditions of [S] there is a divergence between competitive and uncompetitive inhibitors that may be used to identify the type of inhibitor. The equation for Ki also differs. For noncompetitive inhibitors the Ki = I50 and this ... duzzit dishwasher tablets

Web11 Apr 2024 · An uncompetitive inhibitor decreases the apparent value of V max but has no effect on V max /K m. Or, thinking in terms of reciprocals, an uncompetitive inhibitor increases the apparent value of 1/V max but has no effect on K m /V max. In many ways, 'uncompetitive' is a a very poor term.
