Hi Elaine. I am the new user of chimera. I need some help about molecular docking. I have a ligand and its reseptor. I would like to dock ligand to in certain residue in the reseptor. I know where I need to do docking which residue. I need to see a link ligand and residues in the reseptor. 9 Tem 2019 Sal 21:22 tarihinde Elaine Meng <meng@cgl.ucsf.edu> şunu yazdı:
Hi Nail, There is no reason the 3D superposition and RMSD result has to be different. The two scoring methods for sequence alignment might give the same sequence alignment, or even if the sequence alignment is partially different, the iterative 3D fitting starting from the sequence alignment might end up using the same positions of the proteins in the final fit.
If you use the option to show sequence alignment, it will show the sequence alignment and draw light orange boxes on the alignment indicating the positions of the 3D structures used in the final fit.
For more explanation of how Matchmaker works, see the manual page. There is also a publication, if you really want to read even more. < http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/matchmaker/matchma...
I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Hi I superimposed two proteins in chimera with winch algorithms( blossom62) and p250. The result is the same. Why is the result same for both two proteins, although I tried two different algorithm settings? I am using the chimera's MatchMaker tool. The only thing different is the sequence alignment score. I attached the result file. kind regards
