. Parts would have an extensible set of associated metadata that characterizes the part, including for example, performance results, compatibility with other parts, and species, strain, or chassis expression compatability. In this representation, parts should be relatively abstract. For example, they should not include flanking sequences for a particular cloning system. Protein coding parts should be specified as a polypeptide sequence not a DNA sequence so that codon optimization for the target organism can be applied separately.

Similarly, the design tool should allow a user to combine parts to create devices, to combine devices to create systems, and so on. Devices and systems would also have associated performance and compatibility metadata. At all levels of the hierarchy, the specification should be as abstract as usefully possible. An inverter device, for example, might specify the polypeptide sequence of a transcriptional repressor and the target DNA sequence to which it binds, but should not place any constraints on where the repressor DNA coding sequence should be in relation to the target DNA sequence repressed.

This page is a place to park / discuss ideas about future synthetic biology CAD software tools.

Tools ought to be designed like an extensible integrated development environment (IDE) such as Eclipse. Usability should be a primary design gaol. The tools should make work more productive for synthetic biologists from a variety of backgrounds. Tools should work together, sharing a common representation for biological parts, devices, systems, and strains. New functionality ought to be easy to add via a plug-in API, and should be able to take advantage of a common framework for displaying and manipulating DNA sequences, parts, devices, systems, and strains.

Use Scenario

The scenario assumes some capability that we don't yet have.

A user wishes to design and test a new gene regulatory device based on a circuit with a desired feedback topology. She knows the output of the device should be transcription of any gene of interest (PoPS) and the input should be a non-metabolized small molecule.

Using the design tool, she draws circuits that implement her desired topology. The nodes in the circuit are not yet bound to actual biological parts, but are purely defined by abstract parameters such as binding constants and kinetic rates.

Using the simulation tool, she might explore the parameter space of her circuit, collecting data on which combinations of parameters produce an acceptable input / output or dynamic behavior.

She then could use the design tool to search for actual biological components that embody the acceptable parameter sets. If a part doesn’t exist, she can enter a DNA or protein sequence and the create it.

With biological components bound to the circuit, she then uses the assembler to design how the implementing biological components will be introduced into an organism. First she might select an organism (or strain or chassis). A codon optimized DNA sequence for any protein coding components would be created. The cloning and transformation details would all be worked out here. Is she intending to synthesisze the DNA de-novo or clone from existing physical DNA? What cloning / DNA assembly system do the physical parts conform to? What DNA primers need to be ordered?
