One- and two-dimensional proton NMR methods are being used to study the synthetic
operator site O-L1, a 17 base-pair DMA duplex recognized by
repressor and Cro protein. The complete assignment of the 17 imino protons, which participate in Watson-Crick hydrogen bonding, and of the eight adenine H2 protons, which lie in the minor groove of the double helix, is presented.
