Compare the following two proteins  
 
ID 1:
ID 2:

To find the proteins you want to align you can use the auto-suggest feature. It supports searching by
  • PDB ID (e.g. 1cdg)
  • SCOP ID (e.g. d1cdga1)
  • SCOP classification ID (e.g. b.1.18)
  • SCOP stable ID (e.g. 21816)
  • text search (based on SCOP descriptions)
