<* Allergen characterization of BBa_E0020: Not a potential allergen

The Baltimore Biocrew 2017 team discovered that proteins generated through biobrick parts can be evaluated for allergenicity. This information is important to the people using these parts in the lab, as well as when considering using the protein for mass production, or using in the environment. The allergenicity test permits a comparison between the sequences of the biobrick parts and the identified allergen proteins enlisted in a data base.The higher the similarity between the biobricks and the proteins, the more likely the biobrick is allergenic cross-reactive. In the full-length alignments by FASTA, 30% or more amount of similarity signifies that the biobrick has a Precaution Status meaning there is a potential risk with using the part. A 50% or more amount of identity signifies that the biobrick has a Possible Allergen Status. In the sliding window of 80 amino acid segments, greater than 35% signifies similarity to allergens. The percentage of similarity implies the potential of harm biobricks’ potential negative impact to exposed populations. For more information on how to assess your own biobrick part please see the “Allergenicity Testing Protocol” in the following page http://2017.igem.org/Team:Baltimore_Bio-Crew/Experiments

For the biobrick Part:BBa_E0020, there was a 0% of identity match and 0% similarity match to the top allergen in the allergen database. This means that the biobrick part is not of potential allergen status. In 80 amino acid alignments by FASTA window, no matches found that are greater than 35% for this biobrick. This also means that there is not of potential allergen status.

Improvement by Fudan-CHINA 2018

In iGEM 2018, Fudan-CHINA improves this part by taking it apart using BiFC (bimolecular fluorescence complementation).We have compared the improves part with BBa_E0020 and proved our work. You can use our parts as labels for interaction of two target proteins and the location of two proteins in subcellular level, tremendously expanding the usage of the original part and equipping iGEMers another powerful tool for biological visualization.
