Residue-based Diagram editor (RbDe) constructs schematic diagrams of protein sequences to help observe the topology of secondary structure and transmembrane regions; free registration is required to use all features.
RHYTHM predicts buried vs. exposed residues of helical membrane proteins. Users input either primary, secondary or tertiary structure information. Output includes secondary structure and topology information, and the contact type and conservation of each residue.
Sequence Harmony detects subfamily specific functional sites from a multiple sequence alignment by scoring compositional differences between given subfamily groupings.
SLITHER is a web server for protein channel studies. It generates contiguous conformations of a molecule along a curved tunnel inside a protein and calculates the ensuing binding free energy profile.
