Abstract：Pseudoenzymes are proteins that have sequence homology with enzyme families but are proven or predicted to lack enzyme activity due to mutations in otherwise conserved catalytic amino acids. However, pseudoenzymes may be involved in promoting or inhibiting the activity of enzymes, competing with active enzymes for substrates, regulating signal pathways, or serving as protein scaffolds to form protein complex, etc. Although pseudoenzymes have been extensively studied in the medical field, research on the role of pseudoenzymes in plants is still scarce. Recent studies have shown that pseudoenzymes play important roles in stress response, growth, and development in plant. In this paper, multidimensional introduction to pseudoenzymes was provided, including their definition, identification methods, evolutionary processes, and biological roles in plants. Furthermore, the potential roles of pseudoenzymes in plant development regulation were also discussed. This review provides new insights for plant developmental regulation by using pesudoenzymes.
