Introduction
|
This scene shows the two main strands in this protein. Notice the similarity in shape and side chains.
Overall Structure
|
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 here, 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. 1xcs with the side chains displayed (black) visualizes this bonding in the middle region of the protein, again following each strand from blue to red from N to C terminus.
Binding Interactions

Click here to see the binding site.
Additional Features
|
Click here to see that the protein binds directly between strands of DNA. This interrupts the expression of this section of DNA.
Quiz Question 1
|
Why is it important for the protein to bind here?
A unique site is the __ ion found associated with the O6_atom_of_two_guanines, which gives additional strength to the guanine–Co2+–guanine interaction. A Mg2+ B Co2+ C Ba2+ D Mg2+
