Protein Structure Quality Assessment

Discipline: Structural Biology | Tools Used: 5 | Servers: 1

Description

Assess structure quality: basic info, geometry analysis, quality metrics, composition, and visualization.

Tools Used

• calculate_pdb_basic_info from server-2 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool
• calculate_pdb_structural_geometry from server-2 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool
• calculate_pdb_quality_metrics from server-2 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool
• calculate_pdb_composition_info from server-2 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool
• visualize_protein from server-2 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool

Workflow

1. Calculate basic structure info
2. Analyze structural geometry
3. Compute quality metrics
4. Analyze composition
5. Visualize structure

Test Case

Input

{
    "pdb_code": "1AKE"
}

Expected Steps

1. Calculate basic structure info
2. Analyze structural geometry
3. Compute quality metrics
4. Analyze composition
5. Visualize structure

Usage Example

Note: Replace <YOUR_SCP_HUB_API_KEY> with your own SCP Hub API Key. You can obtain one from the SCP Platform.
