Add a Part to the Registry

Members of iGEM teams and labs can add two kinds of parts to the Registry: Basic Parts and Composite Parts.

The most important feature of a standard biological part should be that a user of the part does not have to talk to the part's designer. This is achieved by completely documenting the part.

Parts must have a DNA sequence. Registry users should document, model, characterize, and measure their parts, and provide that information on their part pages.

A part can be identified by its DNA sequence, and may be compatible with several Assembly Standards. A sample of a part may be stored in a plasmid backbone that dictates assembly (ex. pSB1C3), and flanked by the prefix and suffix. The prefix and suffix are never included in the sequence of the part when documented on the Registry, as they are a product of the plasmid backbone, and not the part itself. Sample submission of parts is no longer a requirement for the iGEM competition.

Users can add parts to the Registry that adhere to other assembly standards, however BioBrick RFC[10] and Type IIS are the Registry's current de facto standards; all parts on the Registry that will be considered for the iGEM competition (medals, awards, etc.) must be assembly compatible for BioBrick or Type IIS.

Basic Parts

Basic Parts are discrete functional units of DNA: promoters, ribosome binding sites, protein coding regions, etc. They cannot be subdivided into smaller component parts. DNA for a basic part may be obtained by ''de novo'' synthesis, by primer extension and PCR, or via other techniques. BBa_K863006 is a good example of a well documented Basic Part. Read our help page on adding a basic part.

Composite Parts

Composite Parts are functional units made from an ordered series of basic parts or other composite parts. Explicit base pairs of DNA cannot be entered in as sequence for these parts. The Registry's software provides information and sequence for all the basic parts that you list as components of your composite part. While the Registry provides the sequence from the component parts specified, the function and design issues of the composite part should be documented in detail. BBa_K1150020 is a good example of a well documented Composite Part. Read our help page on adding a composite part.

What's the difference between a basic and composite part?

  • Basic Parts are discrete functional units of DNA. They cannot be subdivided into smaller component parts.
  • Composite Parts are functional units made from an ordered series of basic parts or other composite parts.

In order to create a composite part, each basic part that composes it must already be added and documented to the Registry.

How do I delete a part?

You can delete a part by going to a part's "Hard Information" and setting the DNA status to "deleted".

I synthesized my entire device. Can I add it as a basic part and give it the correct part type?

No, this should be added as a composite part. You should make sure that the basic parts that compose these parts are on the Registry (already exist or you'll be adding them as new basic parts if necessary). You can can go to part tools > edit sequence and features and generate your composite part without BioBrick scars (Blunt Assembly). You can create a small basic part(s) with a part type of "Scar," and enter those in between the basic parts that constitute your composite part.

I want to add a part but do not know the sequence

All users should know their part's sequence before working with it. However, you can still add and document your part and add/edit the sequence later by going to part tools >> edit sequence and features. If you are submitting a sample of your part to the Registry, your part's sequence must be documented before submission per the Registry's submission requirements.

How do I document an improvement on an existing part on the Registry?

There are many different ways to improve an existing part, from adding measurement data to codon-optimization. Please see our help page on contributions. Note that the following page is on how to document different types of contributions or improvements. Make sure to read through the medal criteria for a given iGEM year to understand what the judges are looking for.

We have a part that we'd like to add, but it is not BioBrick RFC10 compatible or iGEM Type IIS compatible

Yes, please add and document it on the Registry. However, this part will not meet the Registry's sample submission requirements.

Should I include the BioBrick prefix and suffix or iGEM Type IIS prefix and suffix in my part's sequence?

No, your part's sequence should not include the prefix and suffix. While your parts should be assembly compatible, the prefix and suffix are an element of the plasmid backbone, not the part.
