Anomalous Michaelis-Menten kinetics in crowded environments (C03/Erg.)

点击翻译按钮获取中文摘要

The diffusion of macromolecules (e. g., proteins) in the interior of living cells differs significantly from that in dilute solutions, which is commonly attributed to the dense packing of cells (“macromolecular crowding”). A cascade of time and length scales governs this anomalous transport and is expected to render the kinetics of chemical reactions anomalous as well. This project is to study the Michaelis-Menten kinetics in the crowded environment of the Lorentz model, combining large-scale simulations of the microscopic model, scaling theory, spatio-temporal chemical master equations, and effective medium theory.
