# Enzyme Inhibitor Design

**Discipline**: Enzyme Pharmacology | **Tools Used**: 5 | **Servers**: 2

## Description

Design enzyme inhibitor: target structure, pocket prediction, compound screening, and ADMET assessment.

## Tools Used

- **`retrieve_protein_data_by_pdbcode`** from `server-2` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool`
- **`pred_pocket_prank`** from `server-3` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/3/DrugSDA-Model`
- **`quick_molecule_docking`** from `server-3` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/3/DrugSDA-Model`
- **`pred_molecule_admet`** from `server-3` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/3/DrugSDA-Model`
- **`calculate_mol_drug_chemistry`** from `server-2` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool`

## Workflow

1. Get enzyme structure
2. Predict active site pockets
3. Dock inhibitor candidates
4. Predict ADMET
5. Check drug-likeness

## Test Case

### Input
```json
{
    "pdb_code": "1AKE",
    "ligand_smiles": "CC(=O)Oc1ccccc1C(=O)O"
}
```

### Expected Steps
1. Get enzyme structure
2. Predict active site pockets
3. Dock inhibitor candidates
4. Predict ADMET
5. Check drug-likeness

## 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).
