Structure-based design strategies

Definition

Structure-based design strategies refer to approaches in synthetic biology and metabolic engineering that utilize the three-dimensional structure of biomolecules to inform and optimize the design of new biological systems or improve existing ones. These strategies rely heavily on computational methods and structural data to predict how changes at the molecular level can influence the function and behavior of biological components, leading to more efficient and effective engineering solutions.
