The billions of proteins that make up life on Earth are almost as numerous as the stars in the heavens, and mapping them is almost as difficult.
In a step toward charting the protein structure universe, scientists funded through the National Institute of General Medical Sciences’ Protein Structure Initiative have just created a map of the protein shapes that nature repeats over and over again to construct the billions of complex proteins that make up life.
The three-dimensional map shows similarities and differences among the protein shapes, letting scientists visualize the organization of all protein structures — the many possible twists, turns and shapes — and see evolutionary changes that may have occurred with time.
