Figure 4

The bridge α-helix hinges and bending. To the right, 10 ns snapshots of closed, closed-Mg and open bridge helices are compared, colored in secondary structure representation, as in Figure 3. G1076, G1080 and G1081 are in space filling representation so that H3 and H4 hinges can be identified. To the left, proposed switch residues β’ H1075, K1079, D1083, R1087, D1090 and β D429 are shown in stick representation for closed-Mg and open TEC bridge helix structures. Blue arrows indicate differences in secondary structure that develop during simulations.
