Figure 2. Fig. 2. Ribbon drawing of a single subunit of AdoHcyase showing three domains: catalytic domain, NAD^+-binding domain, and C-terminal domain. The C-terminal domain from the subunit B is illustrated with white. The bound NAD molecule and Ado* are illustrated by ball-and-stick modes. A, WT structure (open conformation); B, D244E structure (closed conformation).
