The 1xcs (model at right) protein is a small, simple globular protein lacking any clear secondary beta sheets or alpha helices. The protein consists of two non-identical dimers. A simplified model of 1xcs is shown with the side chains removed for clarity. The protein can be followed from N to C terminus following along each strand from blue to red. Note that the strands are antiparallel where they are non-covalently bound. visualizes this bonding in the middle region of the protein, again following each strand from blue to red from N to C terminus.

Click to see that the protein binds directly between strands of DNA. This interrupts the expression of this section of DNA.

Why is it important for the protein to bind ?
A unique site is the __ ion found associated with the , which gives additional strength to the guanine–Co2+–guanine interaction. A Mg2+ B Co2+ C Ba2+ D Mg2+
