In 2022, enabled access to ~1 million Computed Structure Models (CSMs) from AlphaFoldDB and RoseTTAFold (from ModelArchive). now offers access to updated AlphaFold models plus ~68,000 additional CSMs from ModelArchive that include:

  1. Freshwater sponge proteins (modeled with ColabFold, ModelArchive: ma-coffe-slac)
  2. African swine fever virus proteins (modeled with AlphaFold, ModelArchive: ma-asfv-asfvg)
  3. Structural models of the Sphagnum divinum proteome (modeled using AlphaFold2, ModelArchive: 10.5452/ma-ornl-sphdiv)
  4. Hetero-dimer set of proteins from cancer interactome (modeled using AlphaFold, ModelArchive: 10.5452/ma-t3vr3

Exploring PDB Structures and CSMs at

Experimental structures and CSMs are clearly identified throughout the website: a dark-blue flask icon is used for PDB structures and a cyan computer icon for CSMs.

Only experimentally-determined PDB structures are included in search results by default. Move the "Include CSM" from gray- to cyan-colored slider to activate.

Details are available at and described in

Structural motif similarities between PDB structures can provide valuable functional and evolutionary insights. The Structural Motif service finds structures containing a small number of specific amino acids in proximity. This feature looks for residues that appear within 15 Å of each other; the residues may be located far apart in the sequence or appear in different polymer chains.

The search can be launched using the 3D viewer Mol* or through the Advanced Search>Structural Motif option. Documentation help is available.

This service rapidly searches the PDB using the functionality described in Real-time structural motif searching in proteins using an inverted index strategy 2020 PLoS Comput Biol 16(12): e1008502.
