Figure 2

Packing of Leu layers above and below the Cys site of CSL9C trimer shown as spheres. a) Top-down view from N–termini, showing the Leu 5 layer (green) and b) Leu 12 layer (magenta), viewing from C-termini up the helical axis. It shows that metals with stereochemically active lone pair such as As(III), would bind to a coiled coil in an a site such that the lone pair would be housed in the open space towards the C-termini.
