Background/Introduction
One of the main goal in Synthetic Biology is to assess the possibility of building biological systems from interchangeable and standardized parts. In order to provide building blocks, a Registry of physical DNA BioBricks has been established at the MIT. BioBricks can then be assembled to form devices or more complicated systems in living cells.
As in most engineering fields, the challenge begins with a comprehensive description and understanding of the problem. This involves qualitative and quantitative analysis: clear physical interpretation of the problem followed by an adequate mathematical description. Therefore, alongside the effort of characterizing experimentaly the BioBricks , a logical extension to the Registry would be to build a Registry of Biobrick Models to complement the wetlab work.
Motivations behind a Registry of BioBrick Models | |

A key aspect in this effort is the use of a description language being able to describe and support the BioBrick concepts.

Results
In this article, is demonstrated that such Registry of BioBrick Models is achievable. A mock-up is provided based on the great flexibility and modularity offered by CellML.
Generic CellML architecture for BioBricks | |
generic model architectures in CellML are defined for most of the types of the parts encountered in the DNA registry (plasmid, promoter, RBS, proteins, riboswitch ...). | image |
Catalog of quantitative BioBrick models | |
A catalog of quantitative models based on already characterized parts is presented. | image |
Building simulations from modular BioBrick models | |
the versatility of the approach is demonstrated by simulating different sytems from a set of pre-defined models [to be defined]. | image |
Conclusion
Using CellML, a basic Registry of BioBrick models has been built. It takes advantage of CellML flexibility and modularity to provide a catalog of quantitative models which are standardized and reuseable. With the growth of the physical DNA parts and their characterization, such a repository will help to gain a deeper understanding of the BioBrick properties as well a speeding up the process of building-up new devices and systems. But more importantly, it will help to federate the growing number of contributions from the modeling community.
Stuff that we might want to include too
- synergy between the definition of a biobrick model and the way its characterization is done (validation scheme between simulation and experiment)
- future work: CAD system with drag and drop of biobricks and use of 'CellML units' to validate connections between modules,
- elaborate on MIRIAM compliance + touch on linking model with gene and protein databases.
- conclusion is not great ...
