Article Abstract
Proteins exhibit a rich diversity of functional, physico-chemical and biodegradable properties which makes them appealing for various applications in the food and non-food sectors. Such properties are attributed to their ability to interact and assemble into a diversity of supramolecular structures. The present review addresses the updated research progress in the recent field of complex coacervation made from mixtures of oppositely charged proteins (i.e. heteroprotein systems). First, we describe briefly the main proteins used for heteroprotein coacervation. Then, through some selected examples, we illustrate the particularity and specificity of each heteroprotein system and the requirements that drive optimal assembly into coacervates. Finally, possible and promising applications of heteroprotein coacervates are mentioned.

Carvacrol (CAR) is a naturally occurring bioactive compound that is chemically unstable, and microencapsulation technology effectively protects its active components. Casein (CS) and chitosan (CH) were used for the first time as carriers to encapsulate CAR, forming highly stable carvacrol microcapsules (CAR@CS-CH). Under conditions of a 1:1 mass ratio of CS to CH and a pH of 5.

Artificial cells are self-assembled microstructures engineered to replicate the functions of natural cells, such as the capacity to interact and communicate. Until now, communication between artificial and living cells has mainly been based on the exchange of small molecules. An important communication pathway in living systems, however, involves the exchange of bioactive molecules such as neurotransmitters and nucleic acids via their protected transport with vesicles or exosomes.

Complex coacervation has emerged as a powerful model for studying the self-assembly of intrinsically disordered proteins (IDPs) in biological condensates in cells. We characterized the phase behavior and rheology of coacervates formed from peptides with regular repeating sequences to examine the effects of charge patterning and hydrophobicity on coacervate stability and material properties. Our results show that increasing the size of charged blocks enhances salt resistance via electrostatic cooperativity, while incorporating small hydrophobic segments further stabilizes coacervates and increases viscosity through hydrophobic clustering.

Advancing the design and construction of artificial protocells with organized complexity, diverse functionality and practical applicability is urgently demanded in vitro synthetic biology and bioengineering but remains a grand challenge. Here, we present a versatile Pickering emulsion-based encapsulation approach to transform membraneless coacervate compartments into robust multicompartmental hybrid microreactors, which concurrently assimilate the expected attributes of hierarchically compartmentalized structure, molecularly crowded environment, selectively permeable ability and mechanically reinforced stability. Single or multiple biological and non-biological catalytic species can be spatially sequestered in specific domains of the hybrid microreactor, enabling spatiotemporal regulation of individual biocatalysis or divergent cascades with high reaction efficiency.

Spider silks are exceptional biomaterials: biocompatible, biodegradable, and with remarkable mechanical properties. Unfortunately, attempts to replicate them tend to fail due to the difficulty of synthesizing the proteins that constitute them, and to an incomplete understanding of their processing conditions. Here, we report a synthetic system inspired by spider silk, consisting of a synthetic polyelectrolyte with grafted oligoalanine chains.
