Figure 2. Three-dimensional reconstructions of human eNOS holoenzyme in the presence and absence of CaM.
A. Reconstruction of eNOS in the absence of CaM. Two orthogonal views around the vertical axis are shown. The main difference between this reconstruction and the reconstruction of eNOS in the presence of CaM is shown as a pink transparent surface for one of the two monomers in the second view(arrow).
B. Reconstruction of eNOS in the presence of CaM. The arrow in B matches the location of the arrow in A. The bar represents 25 Å.
