FIGURE 3.

Crystal structure of VRN1(208–341). A, structural model of VRN1(208–341) showing that its overall fold is a barrel of β-strands (yellow) capped at each end by short α-helices (red). The 320s loop, which could not be assigned by NMR (potentially due to flexibility), is shown in purple. The conserved N-terminal sequence of VRN1 proteins that is absent in other B3 domains forms a long α-helix (α-N, bottom right of the structure). B, the loop region Glu-321–Val-329 showing 2Fo − Fc electron density contoured at the 1σ level. Images were created in PyMOL (33).
