Protein Structure
Protein structure refers to the sequence and spatial organization of protein molecules, typically categorized into primary, secondary, tertiary, and quaternary levels.
Overview
Spatial conformation mediates biochemical and mechanical functions, such as substrate coordination in enzymatic active sites, receptor signaling through structural shifts, and structural support in fibrous assemblies. Not all functional proteins maintain a static three-dimensional fold or multi-subunit arrangement; many operate with flexible or intrinsically disordered segments. Disruption of normal folding pathways can lead to misfolding and aberrant aggregation associated with various diseases.
Why it matters
Advances in deep-learning prediction systems, such as AlphaFold2, alongside experimental determination methods, have accelerated the structural characterization of proteins across diverse proteomes. These high-throughput structural insights inform targeted therapeutics, biomolecular engineering, and functional annotation.
