Abstract: This project focuses on the characterization of synthetic protein scaffold build with peptide binding domains (ex. SH3, PDZ). By tagging enzymes of a synthetic pathway with the peptides bound by those domains, we promote colocalization of the enzymes. Doing so, the synthetic pathways become more efficient by limiting the intermediary metabolite diffusion. We know this system works in E. coli, but its success is very limited in S. cerevisiae. For more modularity, there is a need to characterize more domain-peptides pairs in this background. Thus, I will test in vivo the interaction strength of multiple domain-peptide pairs in a high throughput fashion. This work uses a protein-fragment complementation assay to characterize protein-protein interaction in yeast. Combined with in silico experiments, this project has the potential to portray the functionality and specificity of exogenous peptide-domain pairs and better predict the success of synthetic scaffolds in yeast.
