Michaelis menten inhibition kinetics

WebbInhibition kinetics: The inhibitory mechanism of cimetidine, triethylamine and diethylamine on pig kidney DAO was analyzed using putrescine as substrate. The analysis included an evalua-tion according to a Lineweaver-Burk plot for a Michaelis-Menten equation, using low substrate concentrations, and for all substrate concentrations WebbKm is theMichaelis-Menten constant, expressed in the same units as X. It describes the interaction of substrate and enzyme in the absence of inhibitor. If the data don't fit the model well, consider instead fitting to a noncompetitiveor uncompetitivemodel. Or fit to the more general equation for mixed-model inhibition.

Webb31 jan. 2024 · Most reaction rates are modeled according to the Michaelis–Menten law (with consideration of activation and inhibition, where known), with some of the parameters obtained from the literature. The missing parameters were estimated by fitting data only for the response of net CO 2 assimilation to CO 2 concentrations. Webb1 jan. 2014 · Reactions that follow Michaelis–Menten kinetics have saturable velocities. Thus, at substrate concentrations much greater than the K m value, the velocity approximates zero-order kinetics, and further increases in substrate concentration do not yield significant increases in velocity.
