Figure 2.
Fig. 2. Surface features near to the FAD-access cavity. Shown are the surfaces of CRY1-PHR (A) and photolyase (B). The electrostatic potential is color-coded on the surface, with red and blue representing areas of negative and positive electrostatic potential, respectively. White line, boundary of the FAD-access cavities in both parts. Figs. 2 and 5C were generated by using GRASP (29).
