From: Cryo-EM analysis of the T3S injectisome reveals the structure of the needle and open secretin
Structure of the InvG secretin pore in the open state. InvG34–557 secretin pore structure viewed from (a) side slab, (b) top (OM perspective) and (c) three monomers highlighting inter-domain and intra-domain packing of monomers i, i + 1 and i + 2. One monomer colored according to structural features as per Fig. 1. Secretin domain β-strand numbers as per our previous closed InvG structure7 indicated in c
