Figure 1.
Figure 1. (a) Overall structure of Arabidopsis cry3. The
N-terminal antenna domain is shown in green, the FAD-binding
domain in grey. The dimeric organisation is shown on the left.
(b) Structural comparison of A. thaliana cry3 with CryDASH from
S. sp. (magenta, 1NP7), A. thaliana cry1 (orange, 1U3D), E. coli
DNA photolyase (blue, 1DNP) and A. nidulans photolyase (cyan,
1TEZ). The MTHF (orange), FAD (yellow) and 8-HDF chromophores
(blue, from the A. nidulans DNA photolyase) are shown with their
molecular surfaces. The N-terminal extension that is a unique
feature of cry3 is coloured in red. (c) Chromophore arrangement
in the E. coli DNA photolyase. This Figure and Figures 2, 3, 4
were prepared by PyMOL [http://www.pymol.org].
