Protein structure prediction

Definition

Protein structure prediction is the computational process of predicting the three-dimensional structure of a protein based on its amino acid sequence. This process is crucial for understanding protein function, interactions, and the development of pharmaceuticals, as it enables researchers to model how proteins fold and how their shapes relate to their biological roles.
