Figure 4. (a) A stereo view of a rib bon diagram of the CBADH tetramer. Monomers are represented in different colors. (b) A side-by-side view of the CBADH tetramer with one monomer removed. A large cavity with a positive (blue) molecular surface potential (left) exists inside the tetramer. This is accessible from outside through narrow channels.
