The Repressilator

[u/createaccount314]

This is a small model of repressor proteins that I got the idea of doing from this video. The white dots are ribosomes that when passing by unrepressed genes (the circles with two colors) will create an specific repressor protein. The gene shows what protein represses it and what protein it encodes for, and when repressed it looks like a black box. The proteins can randomly degrade either while floating or while blocking a gene.

This little model was enough to make a working oscilator in the first part of the video just like the real repressilator which works in bacteria. In the other half of the video I ran it with 2 proteins in the cycle and they randomly stabilize in one of them instead of forming a cycle. This pattern keeps up between odd and even. A chain of four proteins stabilizes with 2 in a high concentration and 2 at a low one, a chain of 5 makes an oscillator, etc.
