A 2026 study in Nature Structural Biology reveals that proteins can achieve the same functional fold through multiple entirely different amino acid sequences. Using cryo-EM and AlphaFold3, researchers found that for a given protein function (e.g., binding ATP), evolution has discovered 7-12 distinct sequence-to-fold pathways, not just the one documented in model organisms. This redundancy is biologically expensive (more DNA, more regulatory overhead) but evolutionarily invaluable: when one pathway is blocked by mutation, others compensate. For drug design, this explains why many promising lead compounds that bind the target protein in vitro fail in vivo - the target folds differently in the cellular environment. Implications: AI drug discovery models must account for fold plasticity, not just static structures.
