Promoterless expression cassette for EYFP +LVA (B0034.E0032.B0015)

Part Structure

The Biobrick encodes LVA-tagged eYFP (BBa_E0032) downstream of the ribosome binding site BBa_B0034. The transcription of eYFP is terminated by the double terminator BBa_B0015. This construct can be used as second cistron expressing a reporter gene in a multicistronic construct.

Mode of Action

TetR binds to the pTet regulator (BBa_R0040) and represses transcription. If the inducer [http://openwetware.org/wiki/ATc anhydrotetracycline (ATc)] is added, tetR action is inhibited and the promoter gets derepressed.

Purpose

This Biobrick was designed for the [http://parts.mit.edu/igem07/index.php/ETHZ ETHZ iGEM 2007 project] and belongs to the constitutive part of the system. In the project description, this part is also termed Part 1. The constitutively synthesized TetR interacts with .... A similar (but not used) construct in this context is BBa_Q04400.
