Synthesis of isotope labeled oligonucleotides and their use in an NMR study of a protein-DNA complex.

Related Articles Synthesis of isotope labeled oligonucleotides and their use in an NMR study of a protein-DNA complex.

Nucleic Acids Res. 1992 Feb 25;20(4):653-7

Authors: Kellenbach ER, Remerowski ML, Eib D, Boelens R, van der Marel GA, van den Elst H, van Boom JH, Kaptein R

The synthesis of an oligonucleotide labeled with 13C at the thymine methyl and 15N at the exocyclic amino groups of the cytosines is described. 13CH3I and 15NH4OH were used as sources of the labels. The labeled oligonucleotide was characterized by several NMR techniques. The duplex possesses a labeled functional group in the major groove at every base pair which makes it a very suitable probe for the study of sequence-specific protein-DNA interaction. The labeled thymine methyl group facilitates the detection of hydrophobic contacts with aliphatic side-chains of proteins. This is demonstrated in an NMR study of a complex between the glucocorticoid receptor DNA-binding domain and the labeled oligomer, which revealed a hydrophobic contact between a thymine methyl group and the methyl groups of a valine residue. There are indications for small differences between the solution structure the X-ray structure of the complex.

Suppression of isotope scrambling in cell-free protein synthesis by broadband inhibition of PLP enymes for selective 15N-labelling and production of perdeuterated proteins in H2O
Suppression of isotope scrambling in cell-free protein synthesis by broadband inhibition of PLP enymes for selective 15N-labelling and production of perdeuterated proteins in H2O Abstract Selectively isotope labelled protein samples can be prepared in vivo or in vitro from selectively labelled amino acids but, in many cases, metabolic conversions between different amino acids result in isotope scrambling. The best results are obtained by cell-free protein synthesis, where metabolic enzymes are generally less active, but isotope scrambling can never be suppressed completely. We show that...

IUBMB Life. 2005 Sep;57(9):615-22 Authors: Ozawa K, Dixon NE, Otting G Modern cell-free in vitro protein synthesis systems present powerful tools for the synthesis of isotope-labeled proteins in high yields. The production of selectively 15 N-labeled proteins from 15 N-labeled amino acids is particularly economic and yields are often sufficient to analyze the proteins very quickly by two-dimensional NMR...

An economical method for producing stable-isotope labeled proteins by the E. coli cel
An economical method for producing stable-isotope labeled proteins by the E. coli cell-free system Abstract Improvement of the cell-free protein synthesis system (CF) over the past decade have made it one of the most powerful protein production methods. The CF approach is especially useful for stable-isotope (SI) labeling of proteins for NMR analysis. However, it is less popular than expected, partly because the SI-labeled amino acids used for SI labeling by the CF are too expensive. In the present study, we developed a simple and inexpensive method for producing an SI-labeled protein...

J Biomol NMR. 1997 Oct;10(3):245-53 Authors: Smith DE, Su JY, Jucker FM The power of heteronuclear NMR spectroscopy to study macromolecules and their complexes has been amply demonstrated over the last decade. The obstacle to routinely applying these techniques to the study of DNA has been the synthesis of 13C,15N-labeled DNA. Here we present a simple and efficient method to generate...
