# Alanine Scanning Mutagenesis Pipeline

**Discipline**: Protein Biochemistry | **Tools Used**: 4 | **Servers**: 3

## Description

Alanine scanning: design scan, compute properties for each mutant, predict interactions, and compare.

## Tools Used

- **`AlanineScanningDesigner`** from `server-28` (sse) - `https://scp.intern-ai.org.cn/api/v1/mcp/28/InternAgent`
- **`ComputeProtPara`** from `server-29` (sse) - `https://scp.intern-ai.org.cn/api/v1/mcp/29/SciToolAgent-Bio`
- **`PredictDrugTargetInteraction`** from `server-29` (sse) - `https://scp.intern-ai.org.cn/api/v1/mcp/29/SciToolAgent-Bio`
- **`calculate_protein_sequence_properties`** from `server-2` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool`

## Workflow

1. Design alanine scan mutants
2. Compute parameters for mutants
3. Predict interactions for mutants
4. Compare protein properties

## Test Case

### Input
```json
{
    "sequence": "MKTIIALSYIFCLVFA"
}
```

### Expected Steps
1. Design alanine scan mutants
2. Compute parameters for mutants
3. Predict interactions for mutants
4. Compare protein properties

## 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](https://scphub.intern-ai.org.cn).
