Molecular Docking Pipeline

Discipline: Structural Biology | Tools Used: 4 | Servers: 2

Description

Complete docking workflow: retrieve protein structure, predict binding pockets, prepare receptor, and dock ligand.

Tools Used

• retrieve_protein_data_by_pdbcode from server-2 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool
• run_fpocket from server-3 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/3/DrugSDA-Model
• convert_pdb_to_pdbqt_dock from server-2 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool
• quick_molecule_docking from server-3 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/3/DrugSDA-Model

Workflow

1. Download protein structure
2. Predict binding pockets
3. Prepare receptor for docking
4. Perform docking

Test Case

Input

    "ligand_smiles": "CC(=O)Oc1ccccc1C(=O)O"
}

Expected Steps

1. Download protein structure
2. Predict binding pockets
3. Prepare receptor for docking
4. Perform docking

Usage Example

Note: Replace sk-b04409a1-b32b-4511-9aeb-22980abdc05c with your own SCP Hub API Key. You can obtain one from the SCP Platform.
