CRYPTOCHROME 3 FROM ARABIDOPSIS THALIANA
Overview
Cryptochromes are almost ubiquitous blue-light receptors and act in, several species as central components of the circadian clock. Despite, being evolutionary and structurally related with DNA photolyases, a class, of light-driven DNA-repair enzymes, and having similar cofactor, compositions, cryptochromes lack DNA-repair activity. Cryptochrome 3 from, the plant Arabidopsis thaliana belongs to the DASH-type subfamily. Its, crystal structure determined at 1.9 Angstroms resolution shows, cryptochrome 3 in a dimeric state with the antenna cofactor, 5,10-methenyltetrahydrofolate (MTHF) bound in a distance of 15.2 Angstroms, to the U-shaped FAD chromophore. Spectroscopic studies on a mutant where a, residue crucial for MTHF-binding, E149, was replaced by site-directed, mutagenesis demonstrate ... [(full description)]
