WebJul 21, 2024 · Two gene of class II photolyases, PiPhr1 (1833 bp) and PiPhr2 (1809 bp), from the Antarctic diatom Phaeodactylum tricornutum ICE-H were cloned, the recombinant proteins expressed and purified. The molecular weight of the recombinant photolyases were determined to be 68 kDa with a pI of 9.04 and 68.82 with a pI of 7.31, respectively. Activity … WebHow would radiation at 220 nm affect a microbial cell? It would deactivate photolyases. It would have little effect, since this wavelength is not easily absorbed by cells. It would cause mutations. It would allow it to photosynthesize. It would allow cells to synthesize vitamin D. It would have no effect. This wavelength is absorbed by.
Photolyase definition and meaning Collins English Dictionary
WebNational Center for Biotechnology Information Photolyases (EC 4.1.99.3) are DNA repair enzymes that repair damage caused by exposure to ultraviolet light. These enzymes require visible light (from the violet/blue end of the spectrum) both for their own activation and for the actual DNA repair. The DNA repair mechanism involving photolyases is called … See more Photolyases bind complementary DNA strands and break certain types of pyrimidine dimers that arise when a pair of thymine or cytosine bases on the same strand of DNA become covalently linked. The bond length of … See more Photolyase is a phylogenetically old enzyme which is present and functional in many species, from the bacteria to the fungi to plants and to the animals.
