## Common Mapping Scenarios

### Example 1: UniProt to PDB
```python
from_db = "UniProtKB_AC-ID"
to_db = "PDB"
ids = ["P01308", "P04637"]
```

### Example 2: Gene Name to UniProt
```python
from_db = "Gene_Name"
to_db = "UniProtKB"
ids = ["BRCA1", "TP53", "INSR"]
```

### Example 3: UniProt to Ensembl
```python
from_db = "UniProtKB_AC-ID"
to_db = "Ensembl"
ids = ["P12345"]
```

### Example 4: RefSeq to UniProt
```python
from_db = "RefSeq_Protein"
to_db = "UniProtKB"
ids = ["NP_000207.1"]
```

### Example 5: UniProt to GO Terms
```python
from_db = "UniProtKB_AC-ID"
to_db = "GO"
ids = ["P01308"]
```

## Usage Notes

1. **Database names are case-sensitive**: Use exact names as listed

2. **Many-to-many mappings**: One ID may map to multiple target IDs

3. **Failed mappings**: Some IDs may not have mappings; check the `failedIds` field in results

4. **Batch size limit**: Maximum 100,000 IDs per job

5. **Result expiration**: Results are stored for 7 days

6. **Bidirectional mapping**: Most databases support mapping in both directions
