Fig. 3. Coordination of anti-cAMP by CRP and CRP*. The
yellow trace is the 3GAP structure (11), and the blue trace is
the CRP* structure. The Ala^128 residue responsible for the
different orientation of the open subunit of the CRP* structure
is indicated by the sphere in the C -helix. The
syn-cAMP observed in only the CRP* structure is shown at the top
of the structures.
