Here I have named two web based and freely available severs which run protein peptide docking. You have to provide protein structure (PDB ID) as target and peptide sequence of length (5-25 amino acids) as ligand.
I found these software reliable. If you have Schrodinger software then you can use Peptide docking of Bioluminate.
If you have to design peptide library (like
overlapping peptide library,
Alanine Scanning Library Truncation Library Positional Scanning Library Random Library Scrambled Library T Cell Truncated Library) from specific sequences of proteins so you can use another web server named "Genescript"
