Part:BBa_K907003

Designed by: Dong-hui Choe, Soo-in Lee   Group: iGEM12_KAIST_Korea   (2012-09-20)

Binary signal generator, promoter reversed, RBS(reverse) - attB - Promoter(reverse) - attP - RBS



<Part Description>

KAIST BBa K907003.png


This part is composed of 3 elements.
1. RBSs: BBa_B0034, upsteam one is reversed
2. Promoter: BBa_J23119, Bacterial constitutive promoter
3. att sites: Recognition site for BBa_K907000(Mycobacterium Phage Bxb1 DNA integrase).


<Binary Signal Generation>
This part promotes transcription and translation of two different proteins one at a time when work with BBa_K907000 and BBa_K907001. By doing so, this device can generate two different signals or binary signal. This binary signal can be further used in variety of modules or even in biological computing in the future.


<Applications>

Initially, this device promotes the transcription and translation of upstream gene due to its promoter orientation. When BBa_K907000(Mycobacterium Phage Bxb1 integrase) recognizes and inverts the sequence flanking with attB and attP sequences, promoter orientation is inverted. Then this device promotes the transcription and translation of downstream gene.


<Part Demonstration>
This device is tested by GFP and mRFP attached construct. See BBa_K907005.
