The claim says that the weakness with allosteric sites is shared by every model tested, whatever its design, rather than being a flaw of one tool. If it holds, it suggests the limit lies in the nature of allosteric binding itself, which matters for drug discovery tools that aim to find allosteric ligands.","findings":["All the AI models modelled orthosteric ligand binding accurately, but all showed a collapse in predicting allosteric complexes.","Orthosteric binding creates dominant energetic funnels through ligand-induced quenching of frustration, while allosteric sites keep neutral frustration landscapes in both apo and holo states.","The authors suggest that conformational heterogeneity and evolutionary plasticity of allosteric sites may hide the recurrent recognition patterns the models are trained to detect."],"terms":[{"term":"orthosteric ligand binding","means":"A molecule attaching at a protein's main, canonical binding site, where its natural partner usually binds."},{"term":"allosteric complexes","means":"Protein-ligand complexes where the ligand binds at a site separate from the main one and changes the protein's activity from there."},{"term":"AI cofolding models","means":"AI systems that predict the 3D structure of a protein together with its bound ligand in a single step."}],"basis":"abstract","abstractFrom":"crossref","model":"claude-sonnet-5-5","writtenAt":"2026-10-13T00:17:05.682Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-13T00:17:05.682Z","attempts":1,"model":"claude-sonnet-5-5","why":null},"note":"Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong.
