Dear Pymol users,
I wish to know how to calculate residue-residue contacts from a PDB file.
Where, contact definition is : two residues are considered to be in contact
if the
minimal distance of their side chain or backbone heavy atoms is < 5.5A ˚ .
Specifically, I want to calculate inter-helical (helix-helix) contacts from
a PDB; when two residues from different helices (transmembrane helixes) are
considered to be in contact if the minimal distance of their side chain or
backbone heavy atoms is < 5.5A ˚
For example, I want to calculate the inter-helical residue contacts of the
PDB "2RH1"
Please advise.
Regards,
Bhumika.
