Re: [ccp4bb] Ligand building

2020-06-13 Thread Barone, Matthias
Hi Hari If I understood you correctly, you want to modify and subsequently dock it onto a complex structure, right? For me, the following workflow turned out to be most straightfwd: - build it in MOLOC (http://www.moloc.ch/). It lets you very easily modify an existing molecule without the

Hi Hari, I typically draw formulae using ChemDraw online, export SMILES and use them to get PDBs/CIFs from Grade web server (Global Phasing). Both ChemDraw and Grade web servers are free to use. Hope that helps, Tomas On Sat, Jun 13, 2020 at 6:01 PM Hari shankar

Hey Mohamed, I am not sure, if this is what you want, but you can import different PEG molecules from coot's "File-> Get monomer". A list of different length PEGs three letter codes can be found on page 1278 of this paper: Naschberger et al., (2016) http://doi.org/10.1107/S205979831601723X. I
