ProteinSyntheseGerüst

ProteinSyntheseGerüst is a conceptual framework in synthetic biology for spatially organizing components involved in protein synthesis. It describes scaffolds that bring together elements such as ribosomes, translation factors, tRNAs, and nascent polypeptides at a common locale. The aim is to improve translation efficiency, co-translational folding, and overall yield in both cellular and cell-free systems.

Designs of ProteinSyntheseGerüst are typically modular. Protein-based scaffolds use engineered binding domains and defined linkers to create a controlled arrangement of translation components. Common interaction motifs or ligand-receptor pairs enable specific docking of each component to the scaffold. Nucleic acid scaffolds, including DNA- or RNA-based platforms, present binding sites through complementary sequences or aptamer–protein interactions. Scaffolds can be encoded genetically within living cells or assembled from purified parts in cell-free environments, offering flexibility in construction and testing.

Applications of ProteinSyntheseGerüst span several areas. In cell-free protein synthesis, scaffolds can boost yields and accelerate production of challenging proteins. For multi-enzyme pathways, scaffolding can facilitate substrate channeling by localizing sequential enzymes, potentially increasing flux and efficiency. In fundamental research, scaffolds provide a tool to study translation dynamics, co-translational folding, and the effects of spatial organization on protein production.

Advantages include enhanced local concentration of components, modularity, and tunable spacing between elements. Challenges involve maintaining scaffold stability and specificity, avoiding unintended interactions, and minimizing metabolic burden on cells. Ongoing work emphasizes design principles, quantitative modeling, and orthogonal interaction modules to improve predictability and performance.
