Figure 2. Structures of a, eNOS[ox] and b, iNOS[ ox] monomers
shown as ribbon diagrams, along with heme, BH[4] and either the
arginine substrate for eNOS[ox] or the inhibitor SEITU for
iNOS[ox], drawn in a ball-and-stick representation. Both
structures are in a similar orientation In this view, the heme
propionate groups are facing away from the viewer BH[4] is
located farther down the cavity and the cavity entrance is on
the opposite side of the monomer. The colors are consistent with
Fig. 3. (a) eNOS[ ox] colored according to each subdomain. (b)
iNOSox painted with the Hue Saturation Brightness color wheel
starting with magenta at the N-terminal residue to red at the
C-terminus.
