Computation-guided redesign of promoter specificity of a bacterial RNA polymerase

Abstract: Synthetic genetic circuits enable precise and dynamic control of gene expression, making them useful tools in metabolic engineering and synthetic biology for regulating cellular responses under transient states, such as metabolic flux and stress. However, the complexity and utility of these systems are restricted by the limited set of available regulatory parts. To engineer circuits with desirable levels of programmable control, these components must be orthogonal from the host expression systems. Bacterial si… Show more

“… 2022 ). In addition, a recent study by Liu et al ( 2022 ) has further defined the role and impact of certain positions of the −35 box on closed complex formation through re-engineering the interaction between the −35 box and the sigma factor, giving a further example of how this knowledge can be used in a promoter engineering context to yield promoter sequences that function orthogonally to the host metabolism.…”

“…Despite intensive study, the DNA binding affinity and specificity of natural proteins remain difficult to predict (4), and the high free energetic cost of desolvating the highly polar DNA surface presents a challenge to the de novo design of new DBPs. For these reasons, while computational de novo design has had considerable recent success in generating binders to arbitrary protein structures (5), mostly at hydrophobic patches, computational approaches for DBP engineering have thus far been limited to redesigning interfaces of existing native protein-DNA complex structures (6)(7)(8)(9)(10). These efforts have been constrained by the rigid geometry of the starting scaffold shape and orientation relative to DNA (11), which restrict the possible target sequences that can be recognized (12).…”
