Comparison of specified structure fragments

[huizhen2014]

Wonderful software, thanks a lot.

I want to the all-in-all search like EFI - Enzyme Similarity Tool function. I found when I took one query for easy-search in uniprot database, I will get thousands hits with different alignment location (from start to end aa). Then, I want do a further separation for theses hits, and I believe If I can extract these aligned structure for each hits to do further all-in-all search. I will get more precise separation for the secondary all-in-all search, which will be enough to point out there cognate substrates.
The aligned structure fragments I want to extract for further search:

The flow is below:

1. search homologous structure, and get hits
2. extract the aligned fragments (fragmented structure) to get the confined hits
3. all-in-all search for the confined hits ( which will hope to figure out the relationship between conserved structure and cognate substrate.

Thanks a lot, or there are alternative methods could help me solve this analysis thought.
