abstract = {We study diffusion of macromolecules in a crowded
cytoplasm-like environment, focusing on its dependence on
composition and its crossover to the anomalous subdiffusion.
The crossover and the diffusion itself depend on both the
volume fraction and the relative concentration of
macromolecules. In accordance with previous theoretical and
experimental studies, diffusion slows down when the volume
fraction increases. Contrary to expectations, however, the
diffusion is also strongly dependent on the molecular
composition. The crossover time decreases and diffusion
slows down when the smaller macromolecules start to
dominate. Interestingly, diffusion is faster in a
cytoplasm-like (more polydisperse) system than it is in a
two-component system, at comparable packing fractions, or
even when the cytoplasm packing fraction is larger.},
