In Vivo Formation of Protein Based Aqueous Microcompartments

In this paper, we report the formation of protein based liquid droplets resulting in the formation of in vivo microcompartments in E. coli or tobacco cells. These microcompartments were generated by expressing elastin-like polypeptides (ELP), which have the ability to undergo a reversible phase transition, resulting in the formation of an aqueous two-phase system (ATPS) in the cytoplasm of the cell. We prove that these microcompartments are …
