Protein Complex Visualization & Analysis

Discipline: Structural Biology | Tools Used: 4 | Servers: 1

Description

Analyze protein complex: download structure, visualize complex, extract chains, and calculate quality metrics.

Tools Used

• retrieve_protein_data_by_pdbcode from server-2 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool
• visualize_complex from server-2 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool
• extract_pdb_chains from server-2 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool
• calculate_pdb_basic_info from server-2 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool

Workflow

1. Download complex structure
2. Visualize protein-ligand complex
3. Extract individual chains
4. Calculate structural statistics

Test Case

Input

{
    "pdb_code": "6LU7"
}

Expected Steps

2. Visualize protein-ligand complex
3. Extract individual chains
4. Calculate structural statistics

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.

    read, write, _ = await stack.enter_async_context(transport)
    ctx = ClientSession(read, write)
    session = await stack.enter_async_context(ctx)
    await session.initialize()
    return session

        ()

        
        result_2 =  sessions[].call_tool(, arguments={})
        data_2 = parse(result_2)
        ()

        
        result_3 =  sessions[].call_tool(, arguments={})
        data_3 = parse(result_3)
