Searching for proteins by primary and secondary structure
Your request is rather specific, so there is no tool...
It is a straightforwards request though. I'd impose the requirement that the structures be solved and no predicted secondary structure. You can ...

Which is the amino acids classification when analyzing the solvent accessibility of a protein?
There is some confusion in the question.
Solvent accessibility of a residue, i.e. the area accessible to the solvent (water), depends on the 3D structure of the protein. It's not a property of an ...

Chou-Fasman Method Overlapping Regions Problem - Secondary Structure Prediction
Sure, an isolated residue has a ψ and φ angles, so you could technically have an isolated residue in a given SS conformation, but that does not mean much if its neighbours' backbones aren't in that ...
