Description

The implementation of [13Cα,13C',15N,2Hα] labelled amino acids into proteins allows the acquisition of high resolution triple resonance experiments. We present for the first time resonance assignments facilitated by this new labelling strategy. The absence of 1JCα,Cβ couplings enables us to measure 1JCα,C' scalar and 1DCα,C' residual dipolar coupling constants using modified HNCA experiments which do not suffer from sensitivity losses characteristic for 13C constant time experiments
