WebDec 21, 2024 · The laboratory work consists in two parts, in which students first determine the enzyme concentration and the time to be used in the following session to obtain the kinetic parameters (K M and V max) by non-lineal fitting of the Michaelis–Menten equation to the initial velocity dependence with substrate concentration results. The experimental ...
WebSep 1, 2024 · The Michaelis-Menten model is used in a variety of biochemical situations other than enzyme-substrate interaction, including antigen-antibody binding, DNA-DNA hybridization, and protein-protein interaction. WebOn day 1 you will do a Michaelis-Menten assay of ADH at pH 9. After that you will build a pH profile of ADH, and then do a Michaelis-Menten assay at a suboptimal pH. Next, you will …
WebThe Michaelis-Menten equation with a competitive inhibitor present: vo= Vmax[S]/(aKM+ [S] ) , where vo= the initial velocity; Vmax= the maximal velocity; KM= the Michaelis constant; a= (1 + [ I ]/KI), and KIis the dissociation constant of the inhibitor, I. We want to determine the value of KIand compare it to KM(or to the KIfor other inhibitors). WebThe Michaelis-Menten equation represents a rectangular hyperbola, with a y-asymptote at the V max value. However, in other cases, more complex kinetic models are required to explain the observed data. Atypical kinetic profiles are believed to arise from the simultaneous binding of multiple molecules within the active site of the enzyme (Tracy ...
WebTroubles begin when they go to the laboratory to perform kinetic experiments and realize that usual laboratory instruments do not measure initial rates but only substrate or product concentrations as a function of reaction time. To overcome this problem we present a methodology which uses the integrated form of Michaelis-Menten equation.
