- | The purpose of the sensor is to increase the production of the RIBOKEY under the control of the intensity of the incident blue light.
| + | |
- | | + | |
- | Input: Blue light (<math>\lambda = 470</math>) <br>
| + | |
- | Output: mRNA_RIBOKEY

- | The biology works as follows, YcgF protein is believed to dimerize upon photo-excitation.
| + | |
- | The YcgE protein is a repressor for the transcription of the mRNA_RIBOKEY, only the dimer form of YcgF is capable of
| + | |
- | interacting with the operator-bound YcgE and to release it from the DNA.
| + | |
- | | + | |
- | The entire network of interactions is visualized in the diagram below
