Streamlining Access to RCSB PDB APIs with Python: Sequence and Models
Webinar hosted by RCSB PDB and the Rutgers Artificial Intelligence and Data Science (RAD) Collaboratory | May 19, 2026
This webinar offers an advanced look at and demonstration of using the rcsb-api Python package, which enables researchers to easily interact with even more RCSB PDB APIs—including Sequence and Models API services.
Using the Sequence API, users can query sequence alignment and annotation data from a variety of external resources. The Models API helps users extract selected structure and ligand coordinates from data files.
Course Objectives and Intended Audiences
After watching the videos in this course, you will be able to:
- Understand the fundamentals of RCSB PDB APIs and their application
- Access sequence-level annotations and alignments with the Sequence Coordinates API and rcsb-api Python package
- Fetch model coordinate data and extract out specific slices or ligands of large structures using the Models API and rcsb-api Python package
- Learn advanced use cases of the search and data APIs using the rcsb-api Python package
- Group search results by sequence similarity and other conditions using the rcsb-api Python package
This course is intended for:
- Software developers who access PDB data
- Bioinformatics and/or structural biology researchers
- Graduate students and postdoctoral scholars in biological sciences
- Faculty members and professionals who utilize PDB data
