The 3 angstrom resolution crystal structure of the Escherichia coli catabolite gene activator protein (CAP) complexed with a 30-base pair DNA sequence 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 …
