Our first system involves using sound as a mechanical force to open a mechanosensitive channel within the E. Coli membrane. This opening allows the transmission of our zinc ion signal to flow into the cell, activating our genetic response system. Particularly, zinc will enter the cytosol and bind to ZntR, a transcriptional activator protein for the gene zntA, which encodes a zinc exporter protein channel, ZntA.

The second system involves a protein-based stress response to sound. The protein BamE is responsible for outer membrane protein assembly, and is shown to be activated by RpoE, the sigma 24 factor of RNA polymerase, as RNA polymerase binds to the bamE promoter for the gene's transcription. RpoE is known for its response to stress that affects outer membrane proteins and membranous lipopolysaccharides.

The Rcs signal transduction system is a two-component stress response that is responsible for maintaining the outer membrane of the E. Coli cell. Proteins RscC and RcsD are inner membrane proteins that direct a signal to RcsB, a cytosolic transcription factor protein that activates a number of genes that synthesize membrane proteins and capsules. More specifically, RcsC is a sensory histidine kinase that autophosphorylates in response to an environmental signal, and then transfers the phosphate group to RcsD, the response regulator.
