Crystal structure and membrane topology of aaPlsY. a View from the membrane plane. The membrane boundary was defined by the OPM server68. TMHs and loops are appropriately labeled. b View from the cytoplasm. c Membrane topology of aaPlsY. Residues with consistent topological assignment between the previous report12 and our structure are highlighted in yellow; the single outlier (Ala121) is highlighted in magenta. Arrows mark helix directions from N to C termini
