the quaternary interactions of escherichia coli dna binding proteins ns1 , ns2 , and ns ( ns1 + ns2 ) have been studied by 1h nmr spectroscopy at 400 mhz following the reversible spectral changes produced by temperature increases on the resonances ( phe ring and his c-2 protons ) whose spectral characteristics reflect the formation and dissociation of either homologous or heterologous interactions .
