FATCAT Home Pairwise Alignment Database Searching Structural Neighbors References Help

Search for Similar Protein Structures by FATCAT (a sample report)

(Try this page if you want to compare structures of close homologs)


Your email: (required, a notice will be sent to you by email once the search is done)
Username: and Password:
(Please input username/password if you would like to protect your result, otherwise leave them blank)

Get your structure (please use only one method from the 3 methods below):
Enter a name for your structure:   (optional)
  • Upload file (in PDB format):    
  • or   Provide PDB code:      Chain:  
  • or   Provide SCOP domain code:  
(Note 1: You can either upload local PDB files or simply provide PDB codes (eg. 1abo) or SCOP domain code (eg. d1mt0a_))
(Note 2: FATCAT server will automatically download the PDB files from RCSB when PDB codes are provided or from SCOP if domain codes are provided)
(Note 3: If your PDB has more than one chain AND you do not want to use the 1st chain, please define the Chain; otherwise, the 1st chain will be used)
(Note 4: Type in "zero" instead of "0" for chain 0; the server will not recognize 0)

** PDB database is updated weekly on every Wednesday.
