In my experience, DALI can be better than SSM at detecting distant structural similarities. You might also want to try CE. To decide if a fold is 'new' rather than 'old but decorated' often boils down to a somewhat subjective call, but asking Alexei Murzin is as good a way as any to decide :-) For

Dear All, I have a few questions about protein structure and fold. I will appreciate your suggestions: We have the crystal structure of a protein and it looks like it might be a new domain. 1) Our structure looks like there are two domains however there are some close interactions between the
