Figure 5
The same packing of hlFBPase in tetragonal space groups. (a) Packing arrangement viewed along the c axis for the molecular-replacement solutions in space groups P4₁2₁2 and P4₃22. (b) The same view for space groups P4₃2₁2 and P4₁22. (c) Packing of the forced I4₁22 setting with a c/3 axis and a crystallographic twofold instead of the observed rNCS. The default setting in the I-centred space group has the origin on the twofold axis along the c axis, leading to the shift compared with (a) and (b), but otherwise the packing is virtually identical. (d) A view rotated 90° compared with (c) shows a complete FBPase tetramer generated by crystal symmetry from the asymmetric unit, which in I4₁22 would be a single subunit.
