Crystal packing interactions. A. Crystal packing of the in vivo-assembled Spx/αCTD complex: the N-terminus of αCTD (labeled N) docks into a crevice formed between the two domains of a symmetry related Spx molecule. B. Crystal packing of the in vitro-assembled Spx/αCTD complex: crystal packing is maintained by both αCTD/αCTD interactions and Spx/Spx interactions. The in vivo-assembled complex αCTD is colored orange and its cognate Spx molecule is colored green. The in vitro-assembled complex αCTD is colored red and its cognate Spx molecule is colored cyan.
