Amino Acid--Base Pairs
Amino Acid-Base Interactions
From this page you can view all 32 calculated interactions between amino acid side chains and unpaired bases containing at least two hydrogen bonds. Some interactions involve the protonated bases, A+ and C+. The eight side chain moieties used to model the interactions are shown below, with grey spheres indicating the carbon atoms connected to the rest of the amino acid. Clicking on an amino acid, followed by selecting a base from a pull-down menu, will display the selected interactions.
