Title: Membrane Enzymes: Artifacts in Arrhenius Plots Due to Temperature Dependence of Substrate-Binding Affinity

Simulations of Arrhenius plots show that an enzyme with a temperature-dependent Km can yield a variety of Arrhenius plot artifacts, most notably erroneous "breaks," if activity is assayed at a fixed substrate concentration.Read More
