Figure 4.
Fig 4. Conservation level of residues mapped onto the structure of 4ANK. Colors represent the conservation level: blue, well-conserved; pink, semiconserved of the same type; green, semiconserved of different type; and yellow, nonconserved. The C-terminal tyrosine is colored in gray. (a) Front (concave) surface of 4ANK. (b) Back surface of 4ANK. The ribbon diagrams on the left show orientations. (c) Longitudinal cross-section of the protein displaying the interior residues. Protein is in the same orientation as in b.
