Abstract
Calibration of the 3JNCγ couplings across the N-Cα- Cβ-Cγ fragment of aspartate and asparagine residues is afforded by two interactions that produce fixed conformations of the side chains in solution. One is the binding of these side chains to calcium ions; the other is the H-bond interaction of these side chains with a backbone amide.
