Overview
In order to prevent cells permanently shifting their metabolism towards one that favours light production, we decided to repress the bioluminescence genes (our optimised lux operon) in the presence of sunlight. The chosen system recognizes the presence of unidirectional UV-A light and comes from the cyanobacterium Synechocystis sp. PCC6803. The system has not been previously characterized before in iGEM. Three components are required to produce a response to UV-A: UirS (UV intensity response Sensor), UirR (UV intensity response Regulator), and PlsiR (promoter of the light and stress integrating response Regulator). For the system to be fully online K322122 is required. This BioBrick is responsible for the synthesis of phycocyanobillin, a chromophore normally found in cyanobacteria that is necessary for the functioning of nearly all light-sensing proteins. We obtained UirS and UirR from genomic Synechocystis DNA via PCR. Our primers included the BioBrick prefix and suffix as well as a ribosome-binding site (B0032). Due to non-BioBrick compatible restriction sites in the UirS gene PCR mutagenesis was carried out with the use of the TOPO TA plasmid vector. The UirR gene contained no such sites and was therefore inserted directly into the pSB1C3 plasmid. PlsiR also lacked such restriction sites and was therefore inserted into pSB1C3.
