Figure 1 Membrane Insertases from M. jannaschii, B. halodurans, and E. coli Membrane insertases from the archaeon M. jannaschii, the Gram-positive B. halodurans, and the Gram-negative E. coli show an increasing complexity. Note the structure of the DUF106 protein is a model of a monomer based on the domain-swapped dimer that was seen in the crystal (Borowska et al., 2015). The coiled-coil region of the M. jannaschii YidC protein, as well as the first TM segment and the N-terminal part of the P1 domain of the E. coli YidC are not seen in the crystal structure because they were disordered in the crystal.
