Briefly, ConSurf-DB gathers sequences similar to that of the protein in question, then constructs a multiple sequence alignment, and analyses it for sequence positions that are conserved (have lower than average differences between sequences) and that are variable (have higher than average differences between sequences). Each amino acid is assigned a conservation score and corresponding color in Proteopedia's interactive 3D molecular scene.
