PDBparam is an online resource for computing several parameters from three dimensional structures of proteins.
The parameters are generally classified into different themes:

1. Identifcation of binding sites
2. Inter-residue interactions
3. Secondary structure propensities
4. Physicochemical properties
Users can calculate their desired parameters for a specific structure by providing the PDB code. For computing the parameters please click on COMPUTE
