Photolyases
WebPyrimidine dinners (induced by UV rays) can be monomerised again by DNA photolyases in presence of visible light. Cleavage of the cyclobutane ring of pyrimidine dimers by DNA photolyases restores the original DNA structure (Fig. 13.15A). Photolyases have chromophores which absorb blue light to provide energy for the reaction. WebPhotolyases exhibit a rather compact structure composed of two distinct domains: an N-terminal α/β domain (residues 1–131, E. coli photolyase numbering) and a C-terminal α …

Biology questions and answers. How would radiation at 220 nm affect a microbial cell? It would deactivate photolyases. It would allow cells to synthesize vitamin D. It would have little effect, since this wavelength is not easily absorbed by cells. It would cause mutations. It would allow it to photosynthesize.
