Characterization of the intermolecular interactions that maintain the dimerization of ScCD8αα. (A) The inter-chain hydrogen bonds of ScCD8αα. The ScCD8αα is shown in cartoon representation with the monomers colored blue and orange. Side chains that assist dimerization through the formation of hydrogen bonds are shown as stick models with their amino acid and position labeled. Hydrogen bonds are shown as red dashed lines. (B) The residues in the interface of the ScCD8αα. ScCD8α is surface rendered in blue. The residues forming the interface are shown as sticks and surface rendered in white while hydrophobic residues are surface rendered in magenta. Amino acid residues and their positions are labeled. (C) Side chains forming the hydrophobic core of ScCD8αα. The backbone of ScCD8αα is shown as a cartoon with the monomers colored blue and orange. The residues forming the hydrophobic core are shown as stick models and colored lime green. Amino acid residues and their positions are labeled.
