NMR Study of the Interaction between the lac Repressor and the lac Operator [PDF]
European Journal of Biochemistry, 1983 Binding of the lac repressor headpiece, the N-terminal region of the lac repressor, to the lac operator of Escherichia coli was studied by 1H-NMR spectroscopy. Two DNA fragments, of 51 base pairs and 62 base pairs, containing the lac operator region, were investigated. The signals of their hydrogen-bonded imino protons were well resolved in the 500-MHz

How lac repressor recognizes lac operator. [PDF]
Proceedings of the National Academy of Sciences, 1978 Nucleotide analogs were substituted for unmodified nucleotides at specific sites in the lac operator sequence by a combination of chemical and enzymatic procedures. The nitrocellulose filter assay was used to study the interactions of these modified operators with wild-type (SQ) and tight-binding (QX86) lac repressors.
