Re: [PyMOL] pymol without GL

[PyMOL] fitting residues
Hello: I was wondering if there was anyway to make the cartoon backbone match the real backbone to a greater extent. Now I have residues displayed as sticks and a backbone displayed as loop and the loop doesn't really come near the residue so it looks like the residue is floating in space. I am looking for a command similar to defining the secondary structure as "turn" in molscript which forces the cartoon through the actual backbone. Thanks in advance.

[PyMOL] Re: fitting residues
Hello: I am trying to color residues off a cartoon loop and want to color the sticks version of the residue down to the Ca, but not the Ca itself (ie. the residue and the cartoon are different colors). The problem is that if I color the Ca, then that section of the cartoon also gets colored. If I don't color the Ca, then the cartoon loop color comes halfway up the bond to the Cbeta. Does anybody have any suggestions, that is if I haven't made the question so convoluted you can understand it. Thanks in advance.

Re: [PyMOL] Polypeptide conformation restriction
Hello: To show the allowed torsion angles, run your protein through procheck (available at http://www.ccp4.ac.uk/main.html), this will show the allowed areas. I would say that the convergence of an MD simlulation cannot be told by torsion angles since the protein conformation with the most allowed angles and/or fastest convergence to allowed regions isn't necessarily the correct one. I have seen some protein structures with a diverse array of torsion angles. What you may get is one of the conformations of the "ensemble" of the transition state to folding (read something by David Baker).

Re: [PyMOL] cartoon_smooth_loops
Hello: You can create more than one object of the same protein, make one smooth loops and display only a small section of that one.

[PyMOL] grasp surfaces

[PyMOL] surfaces
Hello: Okay, I got the surface from Grasp read in by ungrasping it in Raster3d. Now the read in surface loses its electrostatic potential colouring - is there any way to fix this? Cheers, JTM * Jason Thomas Maynes MD/PhD Program Faculty of Medicine University of Alberta ja...@biochem.ualberta.ca *
