Pairwise alignment of protein structures

DaliLite computes optimal and suboptimal structural alignments between two protein structures. It will compare all chains in the first structure against all chains in the second (unless specific chain IDs are given). The resulting superimposed coordinate files can be downloaded or viewed interactively in Jmol.

Important notice: DaliLite will be retired from EMBL-EBI service in August 2015. If you have any questions/concerns please contact us via the feedback link above.

STEP 1 - Enter Coordinates in PDB format
