These "structures of unknown function" (SUFs) are organized by source organism. Select a domain/superkingdom or group (viruses, unclassified) to see all organisms that have SUFs; or jump to popular phyla or classes using the tree of life image below. Making a selection will launch an interactive tree browser. You can also download a text file of all SUF PDB IDs, updated weekly.
