Abstract
Standard methods for de novo protein structure determination by nuclear magnetic resonance (NMR) require time-consuming data collection and interpretation efforts. Here we present a qualitatively distinct and novel approach, called Comparative, Objective Measurement of Protein Architectures by Scoring Shifts (COMPASS), which identifies the best structures from a set of structural models by numerical comparison with a single, unassigned 2D (13)C-(13)C NMR spectrum containing backbone and side-chain aliphatic signals. COMPASS does not require resonance assignments. It is particularly well suited for interpretation of magic-angle spinning solid-state NMR spectra, but also applicable to solution NMR spectra. We demonstrate COMPASS with experimental data from four proteins-GB1, ubiquitin, DsbA, and the extracellular domain of human tissue factor-and with reconstructed spectra from 11 additional proteins. For all these proteins, with molecular mass up to 25*kDa, COMPASS distinguished the correct fold, most often within 1.5*Å root-mean-square deviation of the reference structure.

Protein residue linking in a single spectrum for magic-angle spinning NMR assignment Protein residue linking in a single spectrum for magic-angle spinning NMR assignment Abstract Here we introduce a new pulse sequence for resonance assignment that halves the number of data sets required for sequential linking by directly correlating sequential amide resonances in a single diagonal-free spectrum. The method is demonstrated with both microcrystalline and sedimented deuterated proteins spinning at 60 and 111ÂkHz, and a fully protonated microcrystalline protein spinning at 111ÂkHz, with as little as 0.5Â*mg protein sample.
