Unfolding diversity: Modeling promiscuity and toxicity in the metabolic space and beyond.

The development of in silico whole-cell model organisms is helping to build the interface between high-throughput biological data and predictive biology. I will present the work of our group based on metabolic circuits to design and optimize biological devices for production, sensing and regulation [1], introducing proof-of-concept applications of such devices for smart therapeutics and synthetic biology. Our approach is formally described through graph balance analysis, providing a methodology that can be used to study diverse coupling mechanisms such as promiscuous interactions [2] or toxicity pathways [3]. The integration of pathway information with whole-cell models might ultimately unveil unexpected synergistic effects originated from system perturbations.
