Figure 1. Schematics of the GL1, t-SNARE and TolC.
GL1 is a protein anchored to DOPE lipid, the t-SNARE has a single trans-membrane α-helix and TolC is a trimeric barrel establishing a 14 nm long pore including a transmembrane region made of a 4 nm-wide beta-barrel complex. The plain ellipsoids represent a structured part of the protein outer membrane regions (including both Syntaxin1A and SNAP25 helices in the case of t-SNARE).
