Red light sensor
Single red light inducible construct without downstream genes. This part can be cloned in front of any desired gene product.
Usage and Biology
Red light induces the autophosphorylation at the cytosolic site of cph8. This leads to phosphorylation of OmpR which subsequently binds to OmpC promotor and enables transcription of a following gene. This part needs an envZ deficient strain such as CP919 to function properly, as EnvZ pathway is supposedly also responsible for sensing of aspartate.

Functional Parameters
n/a | Red light sensor |
Induction with red light at 705 nm.
Since OmpR is expressed phosphorylated and therefore gene expression is induced in the dark, red light signalling can be shut down with 650 nm.[1]
