title: Comparison of two different DNA-binding modes of the NF-kappa B p50 homodimer.
abstract: Analysis of the NF-kappa B p50 homodimer bound to different DNA sequences shows that the protein can recognize half-site spacings of either three or four base pairs. The protein can maintain most of its DNA contacts by a relative reorientation of its two domains.
