摘要
Two modifications of the triple-resonance CANCO sequence, designed for backbone assignment in proteins [Angew. Chem. Int. Ed. 43 (2004) 2257], are presented here. These two new sequences display the intra-residue Ca-CO correlation selectively, while in the original sequence both the inter- and the intra-residue correlations were present. In addition, one of the two variants benefits from an improved sensitivity. Both sequences are a useful complement to the CANCO sequence for facile sequence-specific protein assignment by protonless NMR. (C) 2004 Elsevier Inc. All rights reserved.
