SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires boltz, and includes scripts (resource) components.

What problem does it solve?

This Skill addresses the challenge of predicting complex structures for proteins, nucleic acids, and small molecules, providing a powerful tool for validating designed binders, co-folding proteins, and offering an open-source alternative to AlphaFold3.

Core Features & Use Cases

  • Structure Prediction: Accurately predict the structures of protein, nucleic-acid, and small-molecule complexes.
  • Binder Validation: Validate designed binders against a target.
  • Co-Folding: Co-fold a protein with a SMILES or CCD ligand.
  • Open-Source Alternative: An open-source AlphaFold3 alternative with optional binding-affinity prediction.
  • Use Case: If you are a researcher working on protein engineering or drug discovery, this Skill can help you predict the structure of a protein-ligand complex to understand how they interact.

Quick Start

Run the boltz skill to predict the structure of a protein-ligand complex using the provided YAML file 'complex.yaml'.

FAQPage Schema
How do I predict protein, nucleic-acid, and small-molecule complex structures?

To predict protein-ligand complex structures, you can use the Boltz-2 model to co-fold proteins with small molecules or nucleic acids. It accurately predicts these interactions to help you understand binding mechanisms.

Is there an open-source alternative to AlphaFold3 for co-folding proteins with ligands?

Yes, Boltz-2 serves as an open-source alternative to AlphaFold3 for co-folding proteins with SMILES or CCD ligands. It also offers optional binding-affinity prediction for designed binders.

What do I need to validate designed binders against a target protein?

Validating designed binders requires predicting their complex structures with the target protein. Boltz-2 performs this prediction, allowing you to analyze how your designed binder interacts with the target.

Does protein-ligand structure prediction with Boltz-2 require a GPU?

Yes, predicting protein, nucleic-acid, and small-molecule complex structures with Boltz-2 requires a GPU. This hardware is necessary to run the structure prediction computations efficiently.

How do I co-fold a protein with a SMILES or CCD ligand?

You can co-fold a protein with a SMILES or CCD ligand by running the boltz skill with a provided YAML file. This process uses Boltz-2 to accurately predict the resulting complex structure.
