The assignment of aromatic side-chain spins has always been more challenging than assigning backbone and aliphatic spins. Selective labeling combined with mutagenesis has been the approach for assigning aromatic spins. This manuscript reports a method for assigning aromatic spins in a fully protonated protein by connecting them to the backbone atoms using a low-power TOBSY sequence. The pulse sequence employs residual polarization and sequential acquisitions techniques to record H N - and H C -detected spectra in a single experiment. The unambiguous assignment of aromatic spins also enables the characterization of 1 H- 1 H distance restraints involving aromatic spins. Broadband (RFDR) and selective (BASS-SD) recoupling sequences were used to generate H N -Η C , H C -H N and H C -H C restraints involving the side-chain proton spins of aromatic residues. This approach has been demonstrated on a fully protonated U-[ 13 C, 15 N] labeled GB1 sample at 95-100 kHz MAS., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 The Author(s).)
