The Unreasonable Redundancy of Nature's Protein Folds

Replicating Nature's Designs

Scientists have made significant progress in understanding protein structures using deep neural networks. Researchers applied techniques used in language models to biomolecules. This breakthrough has led to a better comprehension of protein folds. The discovery was made possible by advances in generative modeling.

Recent developments in deep neural networks have enabled the creation of powerful generative models for language, images, and videos. These techniques have been successfully applied to biomolecules, allowing researchers to generate and analyze protein structures. Models like DeepMind's AlphaFold have been instrumental in this progress.

Can We Exhaust Nature's Toolbox?

Protein folds are the three-dimensional structures that proteins take on, crucial for their function. Researchers found that despite the vast number of possible protein sequences, nature tends to reuse a limited set of folds. This redundancy is not fully understood and has significant implications for protein engineering and design.

The application of generative models to protein structures has revealed that many proteins share similar folds, despite differences in their sequences. This suggests that the number of unique protein folds is relatively limited. By understanding these folds, scientists can better design new proteins with specific functions.

The discovery of the limited number of protein folds raises questions about the potential for designing entirely new proteins. If nature has already explored most possible folds, can we create novel proteins that are significantly different from those found in nature? Researchers are now exploring this question.
