FIGURE 4 Analysis of S1-mediated crystal lattice packing interactions in <t>FabS1CE-C1:-EPHA2-CRD</t> and FabS1C-C1 structures. (a) Crystal lattice packing arrangement (upper panel) with symmetry mates, and asymmetric unit (lower panel) of (i) FabS1CE-C1: EPHA2-CRD (P3221 space group, trigonal crystal system), (ii) FabS1CE-C1:EPHA2-CRD (P21 space group, monoclinic crystal system), and (iii) FabS1C-C1 (P21 space group). ASU Fab heavy- and light-chains are colored light blue or gray, respectively. Symmetry mate Fab heavy- and light-chains are colored dark blue and green, respectively. EPHA2-CRD is colored magenta. The heavy- and light-chain variable (VH and VL) and constant domains (CH and CL) of the Fab are labeled in (i). (b) S1 substitutions (Q165S and K167Y) and residues in the nearby loop region (N170, A171, L172. S174) cooperate to form crystal lattice packing sites in the following structures: (i) FabS1CE-C1: EPHA2-CRD (P3221 space group), (ii) FabS1CE-C1:EPHA2-CRD (P21 space group), and (iii and iv) FabS1C-C1. NB: In the S1-crystal lattice packing site of FabS1CE-C1:EPHA2-CRD (P21 space group) (ii), the K72 side chain of the packing Fab VH domain remains partially unresolved from the electron density indicating a dynamic interaction.
