ConSurf

Definition

ConSurf is a computational tool used to analyze the evolutionary conservation of amino acid residues in protein sequences. It assigns conservation scores based on multiple sequence alignments, helping to identify functionally important regions in proteins that are evolutionarily conserved across different species. This understanding of conservation can guide researchers in predicting the biological function of proteins and in designing experiments for further exploration.
