	abstract = {A triple-resonance pulse scheme is described which records N-15, NH correlations of residues that immediately follow a methyl-containing amino acid. The experiment makes use of a N-15, C-13 and fractionally deuterated protein sample and selects for CH2D methyl types. The experiment is thus useful in the early stages of the sequential assignment process as well as for the confirmation of backbone N-15, NH chemical shift assignments at later stages of data analysis. A simple modification of the sequence also allows the measurement of methyl side-chain dynamics. This is particularly useful for studying side-chain dynamic properties in partially unfolded and unfolded proteins where the resolution of aliphatic carbon and proton chemical shifts is limited compared to that of amide nitrogens.},

	abstract = {An HMQC-based pulse scheme is presented for the stereospecific assignment of asparagine and glutamine side-chain amide protons. The approach makes use of the recently developed quantitative-J correlation spectroscopy [Bar, A. et al. (1994) Methods Enzymol., 239, 79-105] to distinguish the E and Z primary amide protons and, as such, eliminates the need for assignments derived from more time-consuming and potentially ambiguous NOE methods. An application of this method to a uniformly N-15,C-13-labeled cellulose-binding domain is presented. When used in combination with a NOESY-HSQC experiment, the predominant chi(2) dihedral angles of two asparagine side chains in this protein can also be defined.},

F-19, N-15 and N-14 NMR spectra were simulated using the novel PC program systems DSYMPCD, DCYMPCD and WIN-DAISY running under WIN-NMR. Stereospecific coupling constants were obtained for both isomers.
