# APED: African Protein Engineering Dataset - Thermophile Module
|
| 19 |
|
| 20 |
+
A curated dataset of protein structures from African thermophilic organisms, designed for machine learning applications in protein engineering and heat-stable biologic design.
|
| 21 |
|
| 22 |
+
## Mission
|
| 23 |
|
| 24 |
+
Enable African researchers to computationally design **heat-stable biologics** (vaccines, insulin, diagnostics) that survive supply chains without cold storage.

## Novel Protein Designs
|
| 70 |
|
| 71 |
+
We generated novel thermostable protein backbones using the RFdiffusion → ProteinMPNN → AlphaFold pipeline (based on [Zheng et al., Nature Chemistry 2025](https://doi.org/10.1038/s41557-025-01998-3)).
