Full Protein Characterization

Discipline: Protein Biochemistry | Tools Used: 5 | Servers: 4

Description

Complete protein characterization: validate sequence, compute all properties, predict structure, and analyze pockets.

Tools Used

• is_valid_protein_sequence from server-2 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool
• analyze_protein from server-17 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/17/BioInfo-Tools
• ComputeProtPara from server-29 (sse) - https://scp.intern-ai.org.cn/api/v1/mcp/29/SciToolAgent-Bio
• pred_protein_structure_esmfold from server-3 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/3/DrugSDA-Model
• run_fpocket from server-3 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/3/DrugSDA-Model

Workflow

1. Validate sequence
2. Analyze protein features
3. Compute protein parameters
4. Predict 3D structure
5. Predict binding pockets

Test Case

Input

    "sequence": "MKTIIALSYIFCLVFAGKRDEFPSTWYV"
}

Expected Steps

1. Validate sequence
2. Analyze protein features
3. Compute protein parameters
4. Predict 3D structure
5. Predict binding pockets

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.
