Hey guys,
So if you are still searching for a protein and want to look in each of the CATH or SCOP domains, you can do it from the Protein Data Bank instead of waiting for their individual sites to load. If you go to the homepage at www.pdb.org , on the left hand panel there is a spot to browse the database. If you click on that link, there are tabs near the top of the page that lets you search by biological processes involved, molecular function, domain, etc. Just thought it might help, good luck!

Good tip Callia. The PDB links nicely with CATH and SCOP (and vice versa, if I’m remembering correctly)
