Abstract: A major challenge when optimizing the production of synthetic circuits is minimizing the burden they impose on the shared resources of a host cell. In this work, we employ genome-scale modeling to capture core biosynthetic processes and use these
to explain the ramifications of protein production from synthetic genetic circuits in the model host organism S. cerevisiae. By integrating experimental data from RNA sequencing, proteomics and tRNA microarrays, our model is able to identify limits in the protein production that can be achieved. Our work provides a simplified, comprehensive computational approach to examine the effect of cellular resource limitation in S. cerevisiae expressing different synthetic circuits.
