If it holds, such models could become a route to designing proteins.","findings":["Of 152 experimentally successful designs, 35 have no significant sequence match to known natural proteins, and the rest have a median 27% sequence identity to their nearest match.","For fixed backbone design, the model produced successful designs for each of eight artificially created targets.","For unconstrained generation, the sampled proteins covered diverse topologies, with an experimental success rate of 71/129 or 55%."],"terms":[{"term":"size exclusion chromatography","means":"A laboratory method that separates molecules by size as they pass through a porous material, used here to check whether a protein is a single, non-clumped unit."},{"term":"monomeric","means":"Existing as a single protein chain rather than clumped together or joined with other chains."},{"term":"soluble","means":"Able to dissolve in water-based solution rather than clumping and falling out of it."}],"basis":"abstract","abstractFrom":"crossref","model":"claude-sonnet-5-5","writtenAt":"2026-10-11T01:32:11.686Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-11T01:32:11.686Z","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.
