In order to precisely control the velocity of biochemical reactions, we applied phase separation system coupled with light induction in E.coli.

Phase separation system
We constructed the first artificial phase separation system ever in prokaryotes. These droplets in E.coli exhibit similar spherical shape and high fluidity as they were in eukaryotes. By creating membraneless organelles in a cell, phases could realize the redistribution of various targets, including proteins and small organic molecules.
Photo-activated switch
We use laser as a switch to control our system in a high spatial-temporal resolution. Within a few seconds, target proteins would redistribute into existing phases. After incubated in dark for several minutes, targets can reverse to previous smear state.

Modelling our system
We modelled the phase separation system and coupled enzymatic reactions using a differential equation model and a collision model of chemical reactions. The model conceptually explained how phase separation would regulate downstream reactions, and provided insights for enzyme concentration and phase separation system selection. In addition, an interactive interface based on the model is presented on our wiki.
Downstream reactions
Enzymes of proper size could be recruited into phases by using photo-activated switch. Selecting substrates of proper solubility according to our model, we realized the regulation of enzymatic reactions.

Improvement
Enrichment of CRY2 in phase include both homo-aggregation of itself and hetero-aggregation of CRY2 and CIB1. By introducing point mutation to C terminal of CRY2, we attenuate homo-aggregation of CRY2 in dark, increasing the threshold of light induction. This improvement may also be helpful for teams who want to modify the sensitivity of their light-controlled information-processing system.
Downstream reactions
Enzymes of proper size could be recruited into phases by using photo-activated switch. Selecting substrates of proper solubility according to our model, we realized the regulation of enzymatic reactions.
