Cysteine pairing in the glycoprotein IIbIIIa antagonist kistrin using NMR, chemical analysis, and structure calculations.

Biochemistry. 1993 Jan 12;32(1):282-9

Authors: Adler M, Carter P, Lazarus RA, Wagner G

The pairing of the cysteines in disulfide bonds was investigated for the 68-residue RGD-containing protein kistrin, a potent antagonist of the integrin GP IIbIIIa and an inhibitor of platelet aggregation. Kistrin belongs to a family of homologous proteins found in snake venoms termed disintegrins, all of which have a cysteine content. The disulfide pairing of the 12 cysteines was investigated by chemical analysis, NMR spectroscopy, and distance geometry calculations. The data show that the disulfide pairs are 4-19, 6-14, 13-36, 27-33, 32-57, and 45-64. The various means for assigning the disulfide bonds are described, and the results are compared with the cysteine pairings reported for other disintegrin proteins.

Mammalian production of an isotopically enriched outer domain of the HIV-1 gp120 glycoprotein for NMR spectroscopy Mammalian production of an isotopically enriched outer domain of the HIV-1 gp120 glycoprotein for NMR spectroscopy Abstract NMR spectroscopic characterization of the structure or the dynamics of proteins generally requires the production of samples isotopically enriched in 15N, 13C, or 2H. The bacterial expression systems currently in use to obtain isotopic enrichment, however, cannot produce a number of eukaryotic proteins, especially those that require post-translational modifications such as N-linked glycosylation for proper folding or activity. Here, we report the use of an...	nmrlearner	Journal club	0	06-15-2011 02:31 AM

Analysis of and chemical shifts of cysteine and cystine residues in proteins: a quant Abstract Cysteines possess a unique property among the 20 naturally occurring amino acids: it can be present in proteins in either the reduced or oxidized form, and can regulate the activity of some proteins. Consequently, to augment our previous treatment of the other types of residues, the 13\textC\upalpha and 13\textC\upbeta chemical shifts of 837 cysteines in disulfide-bonded cystine from a set of seven non-redundant proteins, determined by X-ray crystallography and NMR spectroscopy, were computed at the DFT level of theory. Our results indicate that the errors between observed...	nmrlearner	Journal club	0	08-14-2010 04:19 AM
