Insights into intermolecular interactions of SDS22. (a) The SDS22 residues identified as most conserved that are not part of the LRR hydrophobic core are all located on the concave surface of SDS22 (SDS22, blue surface; the most conserved residues are shown as sticks in dark purple). (b) The asymmetric unit of P2₁2₁2₁ SDS22 crystals with SDS22 monomer 1 colored as in (a) and monomer 2 in white. (c) Close-up of the SDS22 residues that form either salt bridges or hydrogen bonds (black dashed lines).
