SIVmac239 Nefcore dimer interface in the P43212 and P212121 crystal forms. (a) Overlay of the two molecules in the asymmetric unit of the P212121 crystal (magenta/green) and two symmetry-related molecules [(x, y, z), (y, x, −z)] in the P43212 crystal (cyan/yellow). The SIVmac239 Nefcore is colored magenta (P212121 crystal) or cyan (P43212 crystal) and the TCRζ polypeptide is colored green (P212121 crystal) or yellow (P43212 crystal). The structures of the lower SIVmac239 Nefcore–TCRζ polypeptide complexes were aligned by least-squares methods. The relative 10° counterclockwise rotation of the top P212121 crystal SIVmac239 Nefcore–TCRζ polypeptide complex is depicted. (b, c) Detailed view of the SIVmac239 Nefcore dimer interface in the P212121 (magenta) and P43212 (blue) crystals. The aligned lower SIVmac239 Nefcore–TCRζ polypeptide complex is colored grey and the side chains of residues involved in the interface are shown as stick models. (b) P212121 crystal form (cyan) is highlighted. (c) P43212 crystal form (magenta) is highlighted. |
