Exploring the Backbone Dynamics of Native Spider Silk Proteins in Black Widow Silk Glands with Solution-state NMR Spectroscopy Exploring the Backbone Dynamics of Native Spider Silk Proteins in Black Widow Silk Glands with Solution-state NMR Spectroscopy Publication date: Available online 13 June 2014 Source:Polymer</br> Author(s): Dian Xu , Jeffery L. Yarger , Gregory P. Holland</br> Spider dragline silk is an outstanding biopolymer with a strength that exceeds steel by weight and a toughness greater than high-performance fibers like Kevlar. For this reason, understanding how a spider converts the gel-like, aqueous protein spinning dope within the major ampullate (MA) gland into a super...	nmrlearner	Journal club	0	06-14-2014 12:53 AM
[NMR paper] Amino Acid Analysis of spider dragline silk using (1)H NMR. Amino Acid Analysis of spider dragline silk using (1)H NMR. Related Articles Amino Acid Analysis of spider dragline silk using (1)H NMR. Anal Biochem. 2013 May 30; Authors: Shi X, Holland GP, Yarger JL Abstract The amino acid composition of N. clavipes dragline silk fiber is determined by conducting (1)H Nuclear Magnetic Resonance (NMR) spectroscopy experiments on acid hydrolyzed material. N. clavipes dragline silk was found to consist of 43.0±0.6% Gly, 29.3±0.2% Ala, 9.1±0.1% Glx, 4.0±0.1% Leu, 3.3±0.1% Tyr, 3.4 ±0.2% Ser, 2.7±0.1%...	nmrlearner	Journal club	0	06-04-2013 06:31 PM

Probing site-specific (13)C/ (15)N-isotope enrichment of spider silk with liquid-state NMR spectroscopy. Probing site-specific (13)C/ (15)N-isotope enrichment of spider silk with liquid-state NMR spectroscopy. Anal Bioanal Chem. 2013 Feb 26; Authors: Shi X, Yarger JL, Holland GP Abstract Solid-state nuclear magnetic resonance (NMR) has been extensively used to elucidate spider silk protein structure and dynamics. In many of these studies, site-specific isotope enrichment is critical for designing particular NMR methods...	nmrlearner	Journal club	0	02-26-2013 06:35 PM
