Limitations such as inadequate inter-enzyme synergy and low operational stability significantly impede their scalable implementation. Thus, achieving precise spatial organization of multi-enzyme systems to emulate synergistic functions and improve stability within artificial environments has emerged as a crucial strategy to overcome existing bottlenecks. This review systematically categorizes multi-enzyme cascade reactions into five modular types (linear, parallel, orthogonal, cyclic, and triangular) and classifies assembly materials into non-biological (synthetic polymer and inorganic material) and biological categories (polysaccharide, nucleic acid, protein, and organism). Drawing on current literature, we systematically examine diverse enzyme assembly strategies, highlight state-of-the-art engineering methodologies, and introduce “ordered assembly” as a novel paradigm for constructing advanced multi-enzyme systems. In consideration of the distinct features of various cascade modules, we further elaborate on design principles for customized assembly strategies and illustrate their implementation through representative case studies.
