Key Lock Antikey
The key/antikey system compares the signal from the blue light and vanillin receptor in order to control vanillin production. The more the measured amount of vanillin exceeds the wanted amount (set by the blue light intensity), the less vanillin is produced. After blue light irradiation, the key is transcribed and ‘unlocks’ the vanillin synthesis pathway. In response to the produced vanillin, the vanillin receptor then activates transcription of the antikey. Key and antikey are complementary RNA-strands: their annealing is favoured over the reaction between key en lock leading to vanillin synthesis.
