Re: [ccp4bb] which software can calculate binding energy

2010-07-23 Thread Dirk Kostrewa
Dear Min, in addition to what Greg Warren wrote, to my knowledge, there is still a big uncertainty in the calculation of desolvation energies. A colleague of mine, a theoretical physicist, when I was at Hoffmann-La Roche, tried to calulcate the desolvation energy contribution to the total

Did anyone using Nano ITC low volume ( 190 ul) for protein interaction? Dear Sir or Madam: Recently, my laboratory buy a Nano ITC low volume ( 190 ul) for protein-ligand interaction or protein-protein interaction. The Nano ITC low volume (190 ul) machine is made by TA instrument. The cell

In addition to what was rightly said, the problem is actually on both, theoretical and experimental, ends. What is taken as experimental value is not very well defined, and figures may vary quite significantly, simply because enthalpy change depends on the precise chemical environment your protein

Hi Andreas, this is the way I do it: I use the program SITUS to convert the volume (in some SITUS-friendly EM format) to a pdb bead model (vol2pdb). Then I'll input that PDB into CRYSOL to generate the theoretical scatter. I vaguely recall that Chimera has a SAXS function (not sure), but

If you used EMAN on single particles (http://blake.bcm.tmc.edu/eman/) proc3d yourmap.mrc dummymap.mrc apix=?.?? calcsf=sf.dat sf.dat gives the F**2/s distribution for the map - with max=0.0 I think so you will need to scale. Steve. Quoting Andreas Förster docandr...@gmail.com: Dear all,

Dear alls I am using ccp4 6.1.2 (ccp4i 2.0.5). When I tried to add project in ccp4i, I received the error message as Application Error, Error: can't read array (/CCP4_DATABA). I can make the new project but the project disappeared once I exit from CCP4I. What is the problem? How can I

Molrep 11.0 is available from here: http://www.ysbl.york.ac.uk/~alexei/molrep.html Several improvements recently, but the main news is a new algorithm of Multi-copy search. Instead of searching for two copies and then for the next two etc. the program constructs larger multimers
