英文摘要 | A sinusoidal modulation scheme is described for selective heteronuclear polarization transfer between two dilute spins in double cross polarization magic-angle-spinning nuclear magnetic resonance spectroscopy. During the second N -> C cross polarization, the C-13 RF amplitude is modulated sinusoidally while the N-15 RF amplitude is tangent. This modulation induces an effective spin-lock field in two selective frequency bands in either side of the C-13 RF carrier frequency, allowing for simultaneous polarization transfers from N-15 to C-13 in those two selective frequency bands. It is shown by experiments and simulations that this sinusoidal modulation allows one to selectively polarize from N-15 to its covalently bonded C-13 alpha and C-13' carbons in neighboring peptide planes simultaneously, which is useful for establishing the backbone connectivity between two sequential residues in protein structural elucidation. The selectivity and efficiency were experimentally demonstrated on a uniformly C-13,N-15-labeled beta 1 immunoglobulin binding domain of protein G (GB1). (C) 2012 Elsevier Inc. All rights reserved. |
