isthaliana Cryptochrome 3 (cry3) structure. Ribbon model of complex A from A. t. cry3 and the repaired CPD damage in sticks representation with SIGMAA-weighted Fobs-Fcalc omit electron density (light blue, contoured at 2 σ) defining the oligonucleotide. The catalytic domain (dark red) of A. t. cry3 contains the catalytic FAD cofactor (yellow) and the antenna chromophore MTHF (orange) in the contact region to the antenna domain (blue). Nomenclature and definition of secondary structure elements are given in (Brudler R. et al. (2003) Identification of a new cryptochrome class: Structure, function, and evolution. Mol Cell 11:59-67.12). Taken from Pokorny et al. (2008).
