How many Mutations are needed to Evolve the Chemical Makeup of a Synthetic Cell?

Abstract

AbstractThe chemical evolution of a synthetic cell endowed with a synthetic amino acid as building block, analog to tryptophan, required the emergence of key mutations in genes involved in, inter alia, the general stress response, amino acid metabolism, stringent response, and chemotaxis. Understanding adaptation mechanisms to non‐canonical biomass components will inform strategies for engineering synthetic metabolic pathways and cells.
