The solution structure and dynamics of the 17-base-pair synthetic operator site OL1, which is recognized by the cI and Cro repressors of bacteriophage lambda, is studied by two-dimensional NMR methods. A sequential assignment strategy for nucleic acids is proposed and illustrated by the assignments of the base and sugar protons of OL1.
