Cation-p Interactions

 

Human Growth Hormone Bound To Single Receptor

PDB: 1A22

TYR-422 and ARG-413

This interaction helps stabilize the tertiary structure of the receptor.

Phosphatidylinositol-Specific Phospholipase C 

From Listeria Monocytogenes


PDB: 1AOD

ARG-247 and PHE-279

This interaction helps stabilize the tertiary structure of the enzyme.

Human Psoriasin

PDB: 1PSR

HIS-86 and PHE-71

This interaction may help stabilize the quaternary structure of the protein.  Is this a cation-p interaction or a p-p interaction?..very interesting!!
