A compositional view comparing modern biological condensates and primitive phase‐separated compartments

Selene M. C. Cannelli,
Ritvik Gupta,
Tan Nguyen
et al.

Abstract: Liquid–liquid phase separation (LLPS) is a process that often occurs due to binding between oppositely charged biopolymers, and has gained increasing attention recently due to their ubiquity in biological systems and ability to direct essential cellular processes. However, while these discoveries in biology are recent, the field of origins of life has been investigating LLPS for nearly 100 years, ever since the first suggestions by Oparin and Haldane that primitive LLPS could have been precursors to the first … Show more

“…Because of the high RNA-peptide LLPS propensity, coacervates have been proposed as a unique environment supporting co-evolution of those species (16). Current studies are now researching the impact of different environments as well as the polymer properties and lengths on the coacervation propensities (43) (44). The bigger construct used in our study, bPTC, is structurally more rigid and interacts with the rPeptides with higher specificity.…”

“…Upon hydration, Fox's proteinoids exhibit a remarkable ability to self-assemble into spherical vesicles. These microspherical membranes serve as a model for the formation of semi-permeable protocell structures from simple abiotic polypeptides [64][65][66][67][68][69].…”
