Cost-effective selective deuteration of aromatic amino acid residues produces long-lived solution 1H NMR magnetization in proteins

Cost-effective selective deuteration of aromatic amino acid residues produces long-lived solution 1H NMR magnetization in proteins

Solution NMR studies of large proteins are hampered by rapid signal decay due to short-range dipolar ¹H-¹H and ¹H-^(13)C interactions. These are attenuated by rapid rotation in methyl groups and by deuteration (²H), so selective ¹H,^(13)C-isotope labelling of methyl groups in otherwise perdeuterated proteins, combined with methyl transverse relaxation optimized spectroscopy (methyl-TROSY), is now standard for solution NMR of large protein systems > 25 kDa. For non-methyl positions, long-lived...

Amino acid selective unlabeling for sequence specific resonance assignments in proteins Amino acid selective unlabeling for sequence specific resonance assignments in proteins Abstract Sequence specific resonance assignment constitutes an important step towards high-resolution structure determination of proteins by NMR and is aided by selective identification and assignment of amino acid types. The traditional approach to selective labeling yields only the chemical shifts of the particular amino acid being selected and does not help in establishing a link between adjacent residues along the polypeptide chain, which is important for sequential assignments. An alternative...	nmrlearner	Journal club	1	03-20-2012 12:42 AM
4D APSY-HBCB(CG)CDHD experiment for automated assignment of aromatic amino acid side chains in proteins 4D APSY-HBCB(CG)CDHD experiment for automated assignment of aromatic amino acid side chains in proteins Abstract A four-dimensional (4D) APSY (automated projection spectroscopy)-HBCB(CG)CDHD experiment is presented. This 4D experiment correlates aromatic with aliphatic carbon and proton resonances from the same amino acid side chain of proteins in aqueous solution. It thus allows unambiguous sequence-specific assignment of aromatic amino acid ring signals based on backbone assignments. Compared to conventional 2D approaches, the inclusion of evolution periods on 1HÎ² and 13CÎ´...	nmrlearner	Journal club	0	09-30-2011 08:01 PM
