Register for the August 11 Virtual Office Hour on the Pairwise Alignment Tool

The Pairwise Structure Alignment Tool can align one or more protein chains to a reference structure in a pairwise manner.

This tool allows for simultaneous analysis and visualization of three-dimensional (3D) structure alignments and structure-based one-dimensional (1D) sequence alignments. The two panels displaying alignment results are interconnected and selecting residues in one panel will select and highlight the same residues in the other panel.

Access the Pairwise Structure Alignment Tool>Pairwise Structure Alignment Tool from the Analyze menu at the top of the page or directly from RCSB.org/alignment. User Guide Documentation is available, with examples of aligning PDB experimental structures with Computed Structure Models (CSMs) from AlphaFold and aligning PDB structures to related enzymes.

Bring your questions about how to use this tool to this virtual office hour with RCSB PDB's Yana Rose on

Monday August 11, 2025
1:00-2:00pm Eastern | 10:00am - 11am Pacific.

Please register for this free event. An institutional email address for registration is preferred.
You will receive confirmation and a Zoom link by email before the event.
