Figure 4

Movement of TM2b as gathered from an overlay of different translocon structures. The position of the colored TM2b is shown relative to the second half of the protein that consists of helixes 6 through 10 (in shades of gray). Closed conformations are represented by the PDB entries 4CG7 in dark blue and 4CG5 in light blue [9], 3J45 in dark red [28]. Partially or fully open conformations: 3J7R in green [29] (Sec61-RNC), 5EUL in orange [30] (SecYEG-pOA-SecA), 4CG6 in cyan [9] (RNC-SecYEG), 3J46 in red [28] (RNC-SecYEG).
