What problem does it solve?
Foldseek enables fast, structure-based similarity searches to detect homologs and similar folds that sequence-based methods may miss, streamlining scaffold discovery and novelty checks for protein designs.
Core Features & Use Cases
- Database searches: Query PDB, AlphaFold DB (afdb50), and clustered databases to find structural neighbors.
- Local and web modes: Run quick, rate-limited queries via the Foldseek web API or perform large-scale searches locally against downloadable databases.
- Configurable thresholds: Tune minimum sequence identity, e-value, and alignment-type to prioritize sensitivity or specificity.
- Practical scenarios: Use for novelty checks (is a design present in AFDB?), scaffold discovery for motif grafting, and clustering designs by structural similarity.
Quick Start
Use the foldseek skill to search design.pdb against afdb50 and return the top 10 hits with alignment metrics and an e-value threshold of 0.001.
