Figure 3
An electrostatic comparison of proteins from the GH105 and GH88 CAZy families. The surface electrostatic potentials of (a) CA_C0359, (b) YteR (PDB entry 2gh4) and (c) UGL from B. subtilis strain 168 (PDB entry 1vd5). The calculated surface electrostatic potentials are color-coded on surface renderings of the three crystal structures (red, negative; blue, positive). The structures are all oriented similarly to display electrostatics down into the active-site pocket. The extended loop of CA_C0359 is indicated by a black arrow. The gate loop in CA_C0359 and YteR is indicated by a red arrow. The smaller inset indicates the ribbon structure visible below the surface rendering to discern orientation details. |
