I am working on a proteomics dataset. I am looking for a tool or service to enrichment analyses using protein IDs as query and provide the class, family, superfamily or fold terms (or class, architecture, topology or hierarchy) as output of enrichment analytics

DAVID had an implementation using SCOP in the past, but after the recent update - they removed it. It was a very useful utility for our drug discovery and nanobioinformatics projects.

I am wondering if there is any other tools/service or package out there to do such protein structure-based annotation and enrichment analyses. Thanks!
