Thanks Jason. It works quite well in case of not very compliated ligands ( e.g bonds beetween aa-tRNA and the aa-tRNA syntase were correct ) but in the sugar-bound enzyme there were some mistakes in representation of the H-bonds netween water/ligand/active center ( some water also partisipate in

Hi Martin, You get three options: (1) You can count alpha carbons: fetch 1rx1, async=0 count_atoms n. CA (2) But, a protein could be missing alpha carbons then this is more complete (and the technique worth noting): n=0 select qq, polymer select pp, None python while cmd.count_atoms("qq"):

Thanks, Thomas, Jason both of the methods are useable :) By the way I've forced with the problem of the representation of the active sites of different enzymes. I need to view all my protein as the cartoons and the ligand as the shpere in the ligand binding pocket. Besides I need to mark residues

Hi Martin, It should be RMSD indeed. Mind that the final RMSD from align is obtained after optimizing the fit by leaving out outliers. Cheers, Tsjerk On Nov 29, 2011 10:07 AM, "Martin Hediger" wrote: Is the RMS the same as RMSD? PyMOL writes "RMS" when using align. Martin Am 11.11.11 14:
