Catalyst-based biomolecular logic gates.

No prior work had fully resolved how biological catalysts might replicate computational decision-making processes within cellular environments. Researchers often struggle to integrate complex signal transduction pathways into predictable, programmable architectures. That uncertainty drove the need to evaluate how enzymatic activity mimics binary operations. Existing frameworks for metabolic regulation frequently lack the modularity required for synthetic design. Scientists have long sought to bridge the gap between natural signaling and artificial logic circuits. This review addresses the conceptual shift toward viewing regulatory networks as information-processing systems.
