3.A.5.6.1
Protein translocase including SecY of 492 aas and 10 TMSs (P25014).  The other subunits were not found in UniProt. SecY is the central subunit of the protein translocation channel. SecYE consists of two halves formed by TMSs 1-5 and 6-10 of SecY. These two domains form a lateral gate at the front which opens onto the bilayer between TMSs 2 and 7, and are clamped together by SecE at the back. The channel is closed by both a pore ring composed of hydrophobic SecY resides and a short helix (helix 2A) on the extracellular side of the membrane which forms a plug.
