There are tools such as hbplus https://www.ebi.ac.uk/thornton-srv/software/HBPLUS/ that will calculate predicted hydrogen bonds (including ligands, you just need to define their chemistry) throughout a structure. These tools usually go beyond simple distance considerations and analyze further geo

Ideally when you place in a modeled proton from the Arg the N--H--O (ligand) should be co-linear. But at 2.6 A N -- O (heavy atom distance), they are almost certain to be h-bonding. On Sun, Jun 6, 2021 at 1:16 PM vivek sharma wrote: > Dear all, > > How does one validate if 2 atoms (non-hydroge
