Figure 1
Overall structure of HpCNH. (a) The refined model fits well into the 1.2σ 2Fo − Fc electron-density map (blue mesh). (b) HpCNH has four protomers in the asymmetric unit, and they are comprised of two tightly packed prototypical CNH dimers, indicated by dimer AB and dimer CD. (c) A cartoon, colored in a rainbow from red at the C-terminus to blue at the N-terminus, of a representative HpCNH protomer reveals the canonical nitrilase fold. The predicted active site is indicated with a molecule of putrescine in a space-filling model based on the structure of MtrCPA (PDB entry 5h8i). (d) A ribbon diagram of superposed protomers, colored in a rainbow from blue at the N-terminus to red at the C-terminus, reveals nearly identical structures. |
