Duplicate each list and use the search and replace feature (selected text only) to make the list of residues to select (resi 1+2+3).Use TextWrangler’s powerful search and replace feature to quickly remove the unneeded text from your list of residues.When you are done selecting all residues, copy all the data from the command line window and paste it into TextWrangler.Each selection will be recorded in the pymol command line window. In the pymol viewer, click each residue to select it.In the pymol command line window, type orient int-profilin.In the pymol viewer, turn off everything but int-profilin.To quickly make the list of residues in the interaction, do the following: Change int-actin in the path to actin when you select the residues to color grey, or use residue number (resi 1+2+3). Copy the residue path from the command line window. Then select each of the residues using the mouse. Turn off all the objects except int-actin. To get the YRB script to color just the residues in the interaction surface, you need to identify all the residues by name so you can exclude them from the object that you will color grey.
Create int - actin, ( interface ) in actin create int - profilin, ( interface ) in profilin
