(a, b, c) Superposition of SP009239–491 (functional monomeric unit; residues 39–366 in magenta and residues 367–491 in violet) with apo FusA (PDB entry 5g5y, light blue) and the FusA–nystose complex (PDB entry 5g60, light orange; Culurgioni et al., 2016). The ribbon models are shown with cylindrical helices. (d) Superposition of SP009239–491 (ribbon model with cylindrical helices in magenta and violet) with the surface representation of apo FusA (light blue) and the FusA–nystose complex (light orange). (e) Ribbon diagram of the structure of SP009239–491 (magenta and violet), highlighting the substrate-binding cavity volume (grey mesh) obtained with POCASA (Zhang et al., 2011). |
