Dynamic Simulation and Mechanical Properties of Microtubules
This work is conducted to obtain mechanical properties of microtubule. For this aim, interaction energy in alpha-beta, beta-alpha, alpha-alpha, and beta-beta dimers was calculated using the molecular dynamic simulation. Force-distance diagrams for these dimers were obtained using the relation between potential energy and force. Afterwards, instead of each tubulin, one sphere with 55 KDa weight ...

متن کاملOn Quantum Mechanical Aspects of Microtubules
We discuss possible quantum mechanical aspects of MicroTubules (MT), based on recent developments in quantum physics. We focus on potential mechanisms for 'energy-loss-free' transport along the microtubules, which could be considered as realizations of Fröhlich's ideas on the rôle of solitons for superconductivity and/or biological matter. In particular, by representing the MT arrangements as c...
متن کاملMechanical properties of brain tubulin and microtubules
We measured the elasticity and viscosity of brain tubulin solutions under various conditions with a cone and plate rheometer using both oscillatory and steady shearing modes. Microtubules composed of purified tubulin, purified tubulin with taxol and 3x cycled microtubule protein from pig, cow, and chicken behaved as mechanically indistinguishable viscoelastic materials. Microtubules composed of...
متن کاملChemical biology meets biological chemistry minireview series.
What is the difference between “biological chemistry” and “chemical biology?” One of us (J. M. G.) received his Ph.D. at an institution where the biochemistry building was called the Laboratory of Chemical Biology, but that was a long time ago, and things have changed. Biological chemistry (or biochemistry), that is the study of life processes at the molecular level, is now quite distinct from ...
