We use bacteria for many things
Bacteria are not only used to make cheese and yoghurt. Humans also use them commercially to produce important molecules like Vitamins and Insuline! - With genetic engineering it is relatively easy to produce simple compounds on a large scale.
Complexity is the aim
One of the biggest challenges nowadays is to engineer whole synthesis pathways into bacteria, for example to produce viable bio-fuel from simple carbohydrates. By encapsulating reactions in bacterial micro-compartments (BMC's), researchers aim to greatly improve the efficiency and complexity of such pathways. However BMC's have limitations, their small size and inability to localize several enzymes in one compartment thus far seems like a roadblock.
We introduce our solution: an engineered phage protein shell!
A recently discovered phage envelops its DNA into a protein shell upon infection of bacteria. We are trying to find the minimal components of this structure so it can be assembled in a bacteria without the phage! - This phage compartment is significantly larger than the BMC's and is shown to be selective in import of not only bacterial but also phage proteins.
