2018 SURF: project description
- Mentor: Richard M. Murray

The goal of this project is to quantify how resources (NTPs, and Amino acids) are depleted during transcription and translation in cell free extract. First some background; we work with cell free extracts which is a purified lysate made from E. coli which we refer to as TX-TL. These extracts are very useful for prototyping and characterizing synthetic biological circuits. When genes are added to this extract they are transcribed to mRNA which are translated into proteins, giving rise to life-like biocircuit functionality. However, TX-TL has a limited lifetime determined in part by the depletion of energetic molecules (namely nucleic acids, amino acids, and ATP) and build up of waste products. The goal of this project is to mathematically model and experimentally characterize resource utilization in TX-TL. Specifically, we would like to build an experimental system to connect a TX-TL reaction to a reservoir of energetic molecules. By varying the size of this reservoir, the depletion rate of fuel molecules will be experimentally controllable allowing for different models of this process to be experimentally tested.
