ProteinMPNN: How It Works (Module 7: The Sequence Finder). Key concept: The inverse folding tool. Explain what ProteinMPNN does and how it produces a sequence for a fixed backbone.

- Explain what ProteinMPNN does and how it produces a sequence for a fixed backbone
- Control the parameters that matter: fixed positions, sampling temperature, number of candidates
- Follow the pipeline from input through model to output
