  "summary": "A fundamental question in structural biology centres around understanding protein evolution. Key to this process is mutational robustness, defined as the protein fold's ability to absorb sequence changes without collapsing its structure. Here, we show that robustness is systematically shaped by simple features such as protein size, geometry, and oligomeric state. We used Foldseek-identified…",
