HNCA-TOCSY-CANH experiments with alternate 13C-12C labeling: a set of 3D experiment with unique supra-sequential information for mainchain resonance assignment
Abstract Described here is a set of three-dimensional (3D) NMR experiments that rely on CACA-TOCSY magnetization transfer via the weak
3 \textJ\textCa\textCa coupling. These pulse sequences, which resemble recently described 13C detected CACA-TOCSY (Takeuchi et al. 2010) experiments, are recorded in 1H2O, and use 1H excitation and detection. These experiments require alternate 13C-12C labeling together with perdeuteration,...

HCCH-TOCSY (0 replies)
Hello everybody,
I am a biologist who has jumped into NMR :(
I hope this is an active forum so that I can improve myself and can help someday to others.
I have a very stupid question!!! Do you know if I can see some HN peaks correlated with C-beta in HCCH-TOCSY?
Cheers,

[U. of Ottawa NMR Facility Blog] Hsqc - tocsy
HSQC - TOCSY
There are many different NMR techniques used to probe molecular structure. Two very useful methods are the HSQC (or HMQC) sequence used to obtain heteronuclear coupling correlations and the TOCSY sequence used to look at extended homonuclear coupling correlations. These are among the most widely used pulse sequences by chemists to help elucidate the molecular structure of organic molecules. The sequences can also be combined into a single HSQC-TOCSY sequence which is simply an HSQC followed by a TOCSY spin lock. For the case of 1H and 13C in organic molecules, the HSQC-TOCSY...

CACA-TOCSY with alternate 13Câ??12C labeling: a 13Cα direct detection experiment for
Abstract We present a 13C direct detection CACA-TOCSY experiment for samples with alternate 13Câ??12C labeling. It provides inter-residue correlations between 13Cα resonances of residue i and adjacent Cαs at positions i â?? 1 and i + 1. Furthermore, longer mixing times yield correlations to Cα nuclei separated by more than one residue. The experiment also provides Cα-to-sidechain correlations, some amino acid type identifications and estimates for Ï? dihedral angles. The power of the experiment derives from the alternate 13Câ??12C labeling with glycerol or glycerol, which allows...
