I have a list of a thousand residues identified on uniprot proteins. I need to gather features of these residues for a classifier. Some features require protein structures. I have a pipeline for finding appropriate structures using the protein model portal, and calculating structure based features (pka, solvent accessibility, disorder, local charge, etc) using published tools. It took a lot of work to scrape the structures and trouble shoot the published tools. I would have rather used pre computed data, but I could not find such a database.
Are you aware of a protein feature database that spans all uniprot proteins? If not, do you know why such a resource has not been built?
