Figure 3

Ribbon diagrams of (CSL19C)3 showing the orientation of Cys side chains. Main chain atoms are shown as green ribbon and the Cys side chain as red sticks with the thiol groups being shown as yellow spheres. a) Top-down view from N termini showing that two Cys side chains are pointing towards the interior of the coiled coil with the third thiol directed towards the helical interface. b) Side view shows that two thiol groups are pointing towards the C- termini of the helical scaffold and the third thiol is almost perpendicular to the helical axis.
