Schematic representation of 2D lattices generated by (A) fusing a Streptag to ALAD (green) and using Streptavidin (yellow) to stitch the structure; or (B) ALAD-Lac21E and ALAD-Lac21K fusions to assemble the array via coiled-coil interactions. Adapted from reference [38•] with permission. (C) Molecular arrangement of 2D sheets obtained with the RIDC3 derivative of cyt cb₅₆₂ in the presence of zinc. The shaded green box contains a single C2-dimer. Three Zn coordination environments enable 2D self assembly. The Zn1 (blue) and Zn2 (orange) sites are formed by the high-affinity coordination motif and the Zn3 site (red) by the low-affinity coordination motif. Adapted from reference [29•] with permission.
