Figure 2
The dimer interface in the VhGlcNAcase crystals. (a) The overall crystal structure of VhGlcNAcase with two identical molecules per asymmetric unit. The GlcNAc product found in the active site of each molecule is shown in a black ball-and-stick representation, with the Fo − Fc electron density shown as a yellow mesh. (b) Surface representation of the dimer in the asymmetric unit. For Mol A, the Cat domain is shown is green, the α+β domain in cyan, the CBD domain in magenta and the linker that joins the Cat and CBD domains in gray. Mol B is represented in gray, while the dimer interface is colored orange. (c) A separate depiction of the dimer interface in the same orientation as in (a), with the dimer interface area highlighted in orange. |
