This illustration depicts a proteoliposome — a spherical bilayer of fat molecules (white and blue) — stabilized in a structure called a zeolitic-imidazole framework composed of zinc and methylimidazole. Inserted into the lipid bilayer — which mimics a cell membrane — are modeled structures of CopA proteins, with a section (in pink) that resides inside [...]
