Blue Light Sensor
Overview
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>)
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
