structural alignment

**Structural Alignment**

Structural alignment is a method used in bioinformatics and molecular biology to compare the three-dimensional structures of proteins or nucleic acids. Unlike sequence alignment, which focuses on the linear arrangement of amino acids or nucleotides, structural alignment assesses the spatial arrangement of atoms to identify similarities and evolutionary relationships between biomolecules. This approach is essential for understanding functional mechanisms, predicting protein function, and guiding drug design by revealing conserved structural motifs and folds across different species or molecular families.
