Register for the May 14 Office Hour on RCSB PDB’s AI-Powered 3D Structure Similarity Search

RCSB PDB's 3D Structure Similarity Search has been redesigned to deliver faster and more scalable structural comparisons across experimentally determined and predicted Computed Structure Models (CSMs).

This new capability improves the accuracy and relevance of 3D Similarity search results on the RCSB.org website, helping users more effectively identify structurally related and distant homolog macromolecules.

The updated 3D similarity search uses machine learning–based embeddings to represent macromolecular structures in a high-dimensional vector space. Combined with vector databases, this approach enables efficient comparison of 3D structures at scale and improves sensitivity to 3D structural similarity, making it well-suited for exploring large collections of predicted models alongside experimentally determined structures.

Learn how to use this new feature that delivers faster and more scalable structural comparisons across experimentally determined and predicted Computed Structure Models (CSMs) in this demonstration.
