Firefly luciferase - luciferase from Photinus pyralis

Firefly luciferase is luciferase from Photinus pyralis. By oxidation of substrate luciferin light is produced. Luciferase thus acts as a reporter protein when connected to other proteins or promoters.

Characterization

In iGEM 2019, we, the iGEM Munich team, characterised the firefly luciferase.

Modification

In iGEM 2016, our team, SYSU-MEDICINE, had constructed a new composite part BBa_K1993006 in order to improve the positioning function of this previous part. Our new composite part contains gene Firefly Luciferase, dTomato and hFTH, which help users observe biological processes in vivo and in vitro.

Improvement of the function

This part was improved by NUDT_CHINA in iGEM 2017 to optimize its function in a dual-luciferase miRNA target expression system. Two restriction sites of BsmBI were added to the 3’ end of firefly luciferase, through which, the 3’ untranslated region of any gene can be inserted using Golden-Gate Assembly, with no worry about the multiple illegal sites contained in it. For more information, please visit our part page: https://parts.igem.org/Part:BBa_K2440008.

Usage and Biology

This part contains a Eukaryotic ribosome binding site and non-standard prefix and suffix. See the sequence first.

We used the part BBa_I712019 to construct the part with split-luciferase. Our sequencing result suggested that this part is completely working. --------Tianjin IGEM TEAM
