Dunaliella salina is a unicellular green alga and possesses two types of photolyase: Class II cyclobutane pyrimidine dimers (CPD) photolyase and (6-4) photolyase. The gene of D. salina (6-4) photolyase is the first one found in unicellular organisms. CPD photolyases have been extensively studied but (6-4) photolyases are less understood. Because of the data observed in this study, D. salina (6-4) photolyase is insensitive to high salinity; whether it can tolerate a higher level of salinity than other (6-4) photolyases needs to be studied further. However, evidence is provided that (6-4) photolyases might be highly conserved among different species, not only in the sequence identity but also in the photorepair mechanism.

UI MeSH Term Description Entries
D011740 Pyrimidine Dimers Dimers found in DNA chains damaged by ULTRAVIOLET RAYS. They consist of two adjacent PYRIMIDINE NUCLEOTIDES, usually THYMINE nucleotides, in which the pyrimidine residues are covalently joined by a cyclobutane ring. These dimers block DNA REPLICATION.

D014466 Ultraviolet Rays That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.
