Figure 3.
Isoelectric surface potential of A. t. cry3 bound to the
single-stranded pentameric DNA containing a CPD analog. (A) Top
and side (Inset) views. (B and C) Hydration and electrostatics
of the active site in the substrate-bound state of cry3. The
black arrows in C indicate the water molecules intruded into the
active site because of replacement of a tryptophan conserved in
class I CPD photolyases by Y434.
