Interaction of the TcB-TcC cocoon with the TcA shell. (A) Top view of the density map corresponding to TcA in the context of ABC(D651A). A circle around the center of the TcA channel and arcs around the outer shell of individual TcA protomers indicate the disruption of C5 symmetry by TcA-A (dashed arc). (B) RMSD of Cα atoms of the individual TcA protomers, plotted on TcA-A. RMSD values (in Å2) increase from blue to red. (C) Interaction of the cocoon (TcB, blue) with 2 of 5 TcA protomers. (Left) Interaction of L702 of TcA-A (red) with V1021 and P1022 of TcB. (Right) Interaction of L702 of TcA-E (ochre) with N997, N998, and T999 of TcB.
