Summary
Chemically reactive coacervates drive self-assembly of products, leading to life-like structures. This platform offers control over supramolecular synthesis and organization within confined spaces.
Area of Science:
- Supramolecular Chemistry
- Chemical Biology
- Materials Science
Background:
- Phase-separated coacervates are known to enhance reaction kinetics and guide self-assembly.
- Coacervates mimic early cellular evolution processes.
- Controlled self-assembly is crucial for advanced materials and understanding life's origins.
Purpose of the Study:
- To introduce and investigate "reactive" complex coacervates capable of self-immolative transformations.
- To demonstrate how these reactive coacervates direct the self-assembly of reaction products.
- To explore the emergence of life-like properties from these self-assemblies.
Main Methods:
- Design and synthesis of "reactive" complex coacervates.
- Induction of chemically triggered self-immolative transformations.
- Analysis of hierarchical self-assembly of reaction products within the coacervate matrix.
- Investigation of coacervate composition effects on reaction rates and product distribution.
Main Results:
- Reactive coacervates successfully undergo self-immolative transformations.
- The reaction products self-assemble hierarchically within the coacervate matrix.
- Emergence of life-like properties, including budding and membrane formation, was observed.
- Coacervate composition was found to critically influence reaction kinetics, product distribution, and self-assembly pathways.
Conclusions:
- "Reactive" coacervates provide a versatile platform for controlling chemical reactions and self-assembly.
- This approach enables controlled supramolecular synthesis and hierarchical self-organization in confined environments.
- The study offers insights into coacervate-mediated processes relevant to pre-biotic chemistry and materials science.

Pinching-off of Coated Vesicles
3.1K
Vesicle budding is orchestrated by distinct cytosolic proteins such as adaptor proteins, coat proteins, and GTPases. To initiate vesicle budding, membrane-bending proteins containing crescent-shaped BAR domains bind to the lipid heads in the bilayer and distort the membrane to form a protein-coated vesicle bud. Adaptors proteins such as AP2 for clathrin-coated vesicles can nucleate on the deformed membrane. Finally, coat proteins such as clathrin or COPI and COPII assemble into a coat forming...

Mechanisms of Membrane Domain Formation
3.0K
Different physical properties of lipids and proteins allow them to localize and form distinct islands or domains in the membrane. Some membrane domains are formed due to protein-protein interactions, whereas others are formed due to the presence of specific lipids such as sphingolipids and sterols—for example, large proteins, such as bacteriorhodopsin, aggregate and create distinct domains.

Vesicular Tubular Clusters
2.4K
After budding out from the ER membrane, some COPII vesicles lose their coat and fuse with one another to form larger vesicles and interconnected tubules called vesicular tubular clusters or VTCs. These clusters constitute a compartment at the ER-Golgi interface known as ERGIC (Endoplasmic Reticulum Golgi Intermediate Compartment). The ERGIC is a mobile membrane-bound cargo transport system that sorts proteins secreted from ER and delivers them to the Golgi.

Cell Motility through Blebbing
1.9K
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.

Yeast Signaling
14.3K
Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...

SNAREs and Membrane Fusion
10.7K
Once a transport vesicle has recognized its target organelle, the vesicular membrane needs to fuse with the target membrane to unload the cargo. Transmembrane proteins called SNAREs present on organelle membranes and their vesicles, mediate vesicle fusion.
SNAREs exist in pairs that symmetrically interact and catalyze the fusion of the lipid bilayers in vesicle and target organelle. v-SNARE in the vesicle membrane are single polypeptide chains that bind to a complementary t-SNARE, composed of 2...
