Artificial assembly of a minimal cell
ABSTRACT Synthetic Biology approaches can assemble and/or reconstruct cell parts in synthetic compartments. A minimal cell as a model for early living cells can be artificially constructed in the laboratory resuming the main properties of a basic cell living system: a synthetic cell compartment or liposome to host a minimal metabolism based on protein synthesis, and a shell and core reproduction mechanism, all in an artificial cell assembly and remaining in the realm of minimal living. It is becoming realistic to construct artificial cells, starting from a minimal cell assembly, and deliver cell-like bioreactors to synthesize pure proteins/enzymes or isolate single pathways. These artificial cell-like systems could perform different tasks in antimicrobial drug development, drug delivery and diagnostic applications.

- "The creation of streamlined synthetic minimal cells will improve our understanding of life and its origins and enable production of natural and unnatural chemical entities (Forster and Church, 2006; Jewett and Forster, 2010; Murtas, 2009; Szostak et al., 2001). This is being approached from two complementary methods. "
ABSTRACT: Cell-free synthetic biology is emerging as a powerful approach aimed to understand, harness, and expand the capabilities of natural biological systems without using intact cells. Cell-free systems bypass cell walls and remove genetic regulation to enable direct access to the inner workings of the cell. The unprecedented level of control and freedom of design, relative to in vivo systems, has inspired the rapid development of engineering foundations for cell-free systems in recent years. These efforts have led to programmed circuits, spatially organized pathways, co-activated catalytic ensembles, rational optimization of synthetic multi-enzyme pathways, and linear scalability from the micro-liter to the 100-liter scale. It is now clear that cell-free systems offer a versatile test-bed for understanding why nature's designs work the way they do and also for enabling biosynthetic routes to novel chemicals, sustainable fuels, and new classes of tunable materials. While challenges remain, the emergence of cell-free systems is poised to open the way to novel products that until now have been impractical, if not impossible, to produce by other means.Metabolic Engineering 09/2011; 14(3):261-9.
