Metabolic capabilities assessment

Definition

Metabolic capabilities assessment is a systematic approach to evaluate and characterize the metabolic functions and potential of an organism or cell system, typically using computational tools and experimental data. This process involves analyzing the metabolic network to identify which biochemical reactions are possible under specific conditions, helping researchers understand the organism's ability to produce desired metabolites or perform specific functions. By reconstructing the metabolic network, scientists can make predictions about metabolic fluxes and optimize engineering strategies for synthetic biology applications.
