Align and compare three-dimensional protein structures to measure how similar their folds are. Using length-independent similarity scores and superposition, these tools evaluate predicted or designed structures, find structural homologs, and detect distant relationships that sequence comparison alone would miss.
  • Input: two or more 3D structures to compare, or a query structure to search against a set.
  • Output: length-independent similarity scores and an optimal superposition quantifying how alike the folds are.
