Crystal structure, at 3 Å resolution, of the E. coli catabolite gene activator protein (CAP) complexed with a 30-base-pair DNA sequence. It shows that the DNA is bent by 90°. This bend results almost entirely from two 40° kinks that occur between TG/CA base pairs at positions 5 and 6 on each side of the dyad axis of the complex (Schultz et al., 1991[link]), PDB ID code 1CGP, as illustrated in the SwissProt images available on the WWW (Peitsch et al., 1995[link]).
