CAP Structure for Modern/Cell Biology    The CAP-DNA Complex.
The E. coli CAP protein is a transcriptional activator that binds to DNA (shown using the Spacefill display). The two subunits of this dimeric protein are shown using the Cartoon display; they are colored blue or green.
The cAMP molecules bound to each subunit are shown as Spacefill with CPK coloring.
