Two models of Tat protein transport. The L-shaped peptide represents the TatA TMH (red) and APH (blue); the TatA C-terminus is not drawn for simplicity. Left, a proteinaceous pore delineated by the TatA TMH (model 1 in text); right, a toroidal pore with TatA TMHs buried under the lipid head groups (model 3 in text). APH, amphipathic helix; TMH, transmembrane alpha helix.
