Getting Closer to Decrypting the Phase Transitions of Bacterial Biomolecules.

Liquid-liquid phase separation (LLPS) of biomolecules has emerged as a new paradigm in cell biology, and the process is one proposed mechanism for the formation of membraneless organelles (MLOs). Bacterial cells have only recently drawn strong interest in terms of studies on both liquid-to-liquid and liquid-to-solid phase transitions. It seems that these processes drive the formation of prokaryotic cellular condensates that resemble eukaryotic MLOs.

Membraneless organelles (MLOs) are a large group of intracellular compartments formed during various stages of a cell life. They are important subcellular structures which enable a cell performance of vital physiological processes including stress response. MLOs can be found in cytoplasm and organelles that are sealed by lipidic membrane, mainly in nucleus.
