Re: [ccp4bb] Slightly OT: crystallization teaching resources for kids

Dear Nicolas, are you sure this concept is correct? The entropy of molecules arranged in a crystal must be greatly larger than in solution. Hence the driving force for crystallisation is actually a drop in energy, and I am not sure there is actually a barrier. I would take the kids to the

Dear All, I would like to bring to your attention the job opportunity outlined below. Please forward to anyone who might be interested in this 11-12 week internship at our West Point, PA, USA site (Req ID ADM008072). IMPORTANT: Please do not reply to this email to apply. Use this link instead:

Re: [ccp4bb] Visualize symmetry operations

Hi Aaron, I have a PyMOL plugin based on cctbx (i.e. it requires the installation of cctbx) that will do this. This allows one to make images like this: http://pldserver1.biochem.queensu.ca/~rlc/work/pymol/pymol_symmetry.png The script is called draw_symops_cctbx.py and is available here:

Dear All, The Department of Biochemistry in the Emory University School of Medicine is seeking to hire an Assistant/Associate Professor (tenure track) with expertise in structural biology and complementary biochemical/ biophysical approaches. The Department of Biochemistry is a leading

Re: [ccp4bb] Slightly OT: crystallization teaching resources for kids

Yes, but the kids will want to know WHY there is an energy barrier. I prefer my explanation below. Happy New Year to all Patrick _ > I am especially needing help with the concept of nucleation, and why nucleation is slower and then crystal growth faster once nuclei have

Re: [ccp4bb] Slightly OT: crystallization teaching resources for kids

Dear Evette, If I was is your situation (explaining nucleation and other concept). I will discuss in terms of energy. I mean obtaining the initial nuclei is the "costly" step in terms of energy. To represent that, out the classical curve of energy, I will use a metaphoric representation

Re: [ccp4bb] Visualize symmetry operations

Hi Aaron may be this tool can be helpful https://symd.nci.nih.gov/ or in the pymol there is script https://pymolwiki.org/index.php/Symmetry_Axis Visualizing the transformation between two selections/objects https://pymolwiki.org/index.php/RotationAxis PDB has a symmetry browser

[ccp4bb] Visualize symmetry operations

Dear CCP4-keteers, Is there a program that can visualize symmetry operation positions (e.g. twofold screws, fourfolds) in protein structures, like CCDC Mercury does for small molecules? Thanks in advance, Aaron -- Aaron Finke Staff Scientist, MacCHESS
