Shaping Liposomes by Cell-Free Expressed Bacterial Microtubules

Genetic control over a cytoskeletal network inside lipid vesicles offers a potential route to controlled shape changes and DNA segregation in synthetic cell biology. Bacterial microtubules (bMTs) are protein filaments found in bacteria of the genus Prosthecobacter. They are formed by the tubulins BtubA and BtubB, which polymerize in the...

Biosynthesis of protein filaments for the creation of a minimal cell

Humanity has achieved to decipher the most fundamental mechanics of cellular life. Nevertheless, despite intense efforts there are still considerable gaps in our understanding of cellular processes. Traditionally, biologists investigate life by observation of existing lifeforms. In order to assign functions to biological components, it is common...

Modelling cell-free RNA and protein synthesis with minimal systems

DNA-guided cell-free protein synthesis using a minimal set of purified components has emerged as a versatile platform in constructive biology. The E. coli-based PURE (protein synthesis using recombinant elements) system offers the basic protein synthesis factory in a prospective minimal cell relying on extant molecules. However, there is an...
