Abstract
Sensitivity and resolution are the two fundamental obstacles to extending solid-state nuclear magnetic resonance to even larger protein systems. Here, a novel long-observation-window band-selective homonuclear decoupling (LOW BASHD) scheme is introduced that increases resolution up to a factor of 3 and sensitivity up to 1.8 by decoupling backbone alpha-carbon (C(?)) and carbonyl (C') nuclei in U-(13)C-labeled proteins during direct (13)C acquisition. This approach introduces short (
