Hi, if you just want a dipeptide, the easiest is probably to build one in PyMOL: Build -> Residue -> Leucine then Proline. You can save it in PDB format using File -> Save Molecule…
You can probably do the same in Coot or JLigand if you want to use CCP4 programs. Hope that helps, Bernhard Bernhard C.

I am investigating the structure-function of a dipeptidase and I would like to dock a dipeptide, substrate (e.g. Leucine-Proline), on the active site but I have no idea where I can get the dipeptides for that. I searched in the PDB but I could not find any. Your help is appreciated Best Regards, Oarabile M. Kgosisejo [email protected]<mailto:[email protected]>
