Figure 4.
Structure of an arrestin2L-(1–393) complex with
clathrin-(1–363).A, ribbon model of the complex shows a
molecule of clathrin-(1–363) (green) with two molecules of
arrestin2L-(1–393) (cyan) using two independent binding
interfaces. The boxed area (red) is an additional interface
using the splice loop of arrestin2L. B, multiwavelength
anomalous diffraction electron density maps (σ = 1.5) showing
the splice loop of arrestin2L (top) and detailed structure of
the boxed area from A with labeled key residues of arrestin2L
and clathrin (bottom; black and green, respectively). C, B is
depicted as a one-dimensional map noting possible hydrogen
bonding (dotted lines) and hydrophobic interactions (bold dotted
lines).
