WebFine mapping narrowed down BnaC08cqDTF to an 86-kb region on chromosome C08. The region harbored fifteen genes. After comparative analyses of the DNA sequences for mutation between A and C syntenic regions and detected by RNA-seq and qRT-PCR between the two parents, we found that BnaC08G0010400ZS harbors an A/G nonsynonymous … WebApr 1, 1994 · Structure and Function of DNA Photolyase and Cryptochrome Blue-Light Photoreceptors.

WebJun 1, 2009 · This enigmatic photoreactivation process was soon correlated with the function of DNA photolyases [1], which utilize blue light to clean the bacterial genome from UV-induced lethal lesions. The field of the photolyase/cryptochrome family has been summarized in a number of excellent reviews [2••, 3]. WebJun 30, 1995 · Photolyase repairs ultraviolet (UV) damage to DNA by splitting the cyclobutane ring of the major UV photoproduct, the cis,syn-cyclobutane pyrimidine dimer (Pyr<>Pyr). The reaction is initiated by blue light and proceeds through long-range energy transfer, single electron transfer, and enzyme catalysis by a radical mechanism.

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 this dimerization is shorter than the bond length of normal B-DNA structure which produces an incorrect template for replication and transcription. The more common covalent linkage involves the formation of a cyclobutane bridge. Photolyases have a high affinity … ds win terminbuchWebStructure and Function of DNA and RNA.
