The core of this approach is the "Site to Distance" principle. This principle guides the placement of specific amino acid residues within a peptide sequence to optimize their interaction with ice surfaces. By precisely controlling the spatial arrangement of these residues, scientists can engineer peptides that effectively bind to ice crystals, thereby preventing their growth and aggregation. This meticulous approach ensures that the design of these synthetic peptides is not left to chance but is guided by empirical and theoretical insights into the molecular mechanisms of ice interaction.

The de novo design of antifreeze peptides involves more than just mimicking natural AFPs. It offers unprecedented means to advance our understanding of how ice-binding occurs and to create novel functional amyloid protein (AFP) mimetics.作者：X Zhang·2025·被引用次数：5—Here, we describe a “Site to Distance”principleforde novo designof AFPTs, in terms of understanding their structure–activity relationships. This de Novo Design strategy has been particularly successful in generating peptide sequences that exhibit excellent ice-binding and antifreeze activity. For instance, a key step in this design workflow involves identifying specific "E spots" – the most effective ice-binding sites. These sites, which can bind ice up to four times more effectively than natural ice-binding sites (IBS), are then strategically inserted into a candidate peptide backbone. Subsequent steps leverage computational platforms, such as low-temperature antifreeze peptide structure prediction tools, to further refine the design based on these identified IBS.作者：X Zhang·2023·被引用次数：23—In this work,three low immunogenic antifreeze peptidesare developed based on the functional motif of the Tenebrio molitor antifreeze protein (TmAFP).

The design and synthesis of peptides that exhibit ice-binding and antifreeze activity often involves creating structures like single-ring or double-ring cyclic peptides, or even dendrimeric polypeptides. For example, a strategy for the design and synthesis of peptides that exhibit ice-binding and antifreeze activity involves the creation of 9-14 amino acid polypeptides, into which four semi-bound amino acids are inserted.
