Figure 3. Crystal Structure of the DGKSAM Polymer
(A) Space-filling model of the DGKSAM polymer showing the helical structure. Every other subunit is colored green or yellow. Two of the subunits are shown as ribbon diagrams.
(B) A ribbon model showing a close-up view of the oligomeric interface. The end-helix (EH, green) surface of one SAM domain contacts the mid-loop (ML, yellow) surface of another SAM domain forming head-to-tail interaction. Side-chains important in mediating this interaction are shown and colored according to the surface on which they reside. For sequence orientation: The V52, G53, K56, E35G, and D43 in the DGKSAM structure correspond to V1148, G1149, K1152, E1131, D1139, and C1116 in the full-length DGKδ1.
