Biologistics: How fast do chemical trains move in living cells?
Date:1/31/2013

sport results from random fluctuations, in addition occurring in a small volume, where viscosity depends not only on the medium, but also on the size of the viscosity probe! I wish good luck all those who want to transfer processes occurring in physically so different environment to our roads. Biologistics works excellent, but inside cells only!".

Supported by grants from the National Science Center and the Ministry of Science and Higher Education as well as by programs from the Foundation for Polish Science, the research published in the "Bioinformatics" journal focused on the rate of diffusion of protein molecules in the Escherichia coli cytoplasm.

"The viscosity inside mammalian cells is relatively low, only 60 times higher than that of water. But bacteria are considerably smaller, everything is more crowded. The macroscopic viscosity there is up to 26,000 times higher than that of water. This is really dramatic difference!", concludes Dr Tomasz Kalwarczyk (IPC PAS).

Earlier research of Prof. Hołyst's team allowed for concluding that viscosity experienced by molecules is not only medium, i.e., solvent dependent, but also depends on the size and shape of molecules. Therefore, in the same medium, molecules differing in shape and size can experience very low viscosity (nanoviscosity) or macroscopic viscosity that is up to several thousand times higher. The previous methods for predicting diffusion coefficients in cytoplasm have not accounted for the effect.

Experimental determination of the diffusion rates of chemical compounds in bacterial cells is both time consuming and difficult. As a result, diffusion coefficients have been measured only for a very limited number of compounds in only some bacterial cells. That's why the researchers from the IPC PAS developed a method for predicting diffusion coefficients for various compounds and media. For that purpose they used their own formulae, accounting for nanovisco
