Variation in the crystal contact hydrogen-bond network. Overlay of the crystal-packing interface between two asymmetric units of the P212121 crystal lattice (SIVmac239 Nef is shown in magenta and TCRζ is shown in green) and two symmetry-related molecules (y, x, −z) and (1/2 + y, 1/2 − x, 1/4 + z) of the P43212 crystal lattice (SIVmac239 Nef is shown in cyan and TCRζ is shown in yellow). Alignment was performed by least-squares methods using one SIVmac239 Nef–TCRζ polypeptide complex [at the bottom in (a)]. Hydrogen bonds present in the crystal lattices are represented by dashed lines and are colored green and yellow for the P212121 and P43212 crystal forms, respectively. |
