Improved NMR spectra of a protein–DNA complex through rational mutagenesis and the application of a sensitivity optimized isotope-filtered NOESY experiment

Abstract
The NMR spectra of the complex between the DNA-binding domain of the Dead ringer protein (DRI-DBD, Gly262-Gly398) and its DNA binding site (DRI-DBD:DNA, 26 kDa) have been optimized by biochemical and...
