Volatile diffusional character of cytoplasm.
The fluctuating extracellular environment of microbial organisms influences diffusional mobility of macromolecules in the cytoplasm. This effect may be measured experimentally on the one hand by directly tracking the trajectories of individual macromolecules. We discuss how it may also be indirectly estimated from fluctuations in the amount of cytoplasmic water and from the varying patterns of protein expression seen in 2d gel analysis.
