Figure 5.
FIGURE 5. Effector sites 1 and 2 of cN-II with bound
adenosine and sulfate. Omit F[o] - F[c] maps are covering
adenosine with  level of 4.5 in
effector site 1 and level of 3 in effector
site 2. A, stereo image of adenosine bound in effector site 1,
with adenosine and amino acid residues colored in turquoise. B,
stereo image of effector site 1 from two adjacent subunits
connected through interface A. Salt bridges are indicated by the
dotted lines. Nitrogens are shown in blue, oxygens in red, and
sulfur in yellow. C, stereo image of adenosine bound in effector
site 2. Note that the ribose moiety is disordered so that the
electron density cannot confirm its location. Waters are colored
in red. Polar atoms are color-coded as following: nitrogen in
blue, oxygens in red, and sulfur in yellow.
