The Killer Red Construct is a double condition suicide sequence. The first condition is the presence of mercury. When the bacteria are in an environment containing mercury, the production of RBS (BBa_B0030) is initiated through the Promotor (BBa_K346002). Then, the Killer Red protein (BBa_K1184000) is produced. The second condition is the presence of light. In order for the Killer red to activate, light (540-585 nm) needs to be shined onto the bacteria to initiate the reaction.

Mercury activated Killer Red Protein suicide switch

The Killer Red Construct is a double condition suicide sequence. The first condition is the presence of mercury. When the bacteria are in an environment containing mercury, the production of RBS (BBa_B0030) is initiated through the Promotor (BBa_K346002). Then, the Killer Red protein (BBa_K1184000) is produced. The second condition is the presence of light. In order for the Killer red to activate, light (540-585 nm) needs to be shined onto the bacteria to initiate the reaction.

Usage and Biology

This part is designed to work in conjunction with a mercury accumulator device, specifically part BBa_K1355003 designed by the iGEM14_UFAM_BRAZIL team.

We chose to use BBa_B0030 as a moderate binding RBS in order to allow a delay in the expression of Killer Red protein in relation to the accumulator.
