Hello,
Can you suggest how to make isopeptide bond in coot and
Hi Amit,
If you are interested in generating restraints for SHELX then Grade2 supports
this (apply the cosine rule like Jon suggests) and producing ‘dfix’ files
for SHELXL (is this what you mean by a “shelxl” topology file)?
The Grade Web Server:

can be used
Hello Amit, without PRODRG I don't know of another way to make the SHELX
dictionary restraints but it can be done by hand with a small-molecule
structure to measure the bond lengths and 1-3 atom distances from. You can also
use general values for the ideal bond lengths and angles and the cosine
