The apparent increase in solar ultraviolet (UV) radiations on the Earth's surface, due to
continuous depletion or diminishing of the stratospheric ozone shield has triggered serious …

Light is a very important environmental factor that governs many cellular responses in
organisms. As a consequence, organisms possess different kinds of light‐sensing …

Light is essential for the life of photosynthetic organisms as it is a source of energy and
information from the environment. Light excess or limitation can be a cause of stress …

Photolyases and cryptochromes form an almost ubiquitous family of blue light
photoreceptors involved in the repair and maintenance of DNA integrity or regulatory control …

Many DNA-processing enzymes have been shown to contain a [4Fe4S] cluster, a common
redox cofactor in biology. Using DNA electrochemistry, we find that binding of the DNA …

The cryptochrome/photolyase (CRY/PL) family represents an ancient group of proteins
fulfilling two fundamental functions. While photolyases repair UV-induced DNA damages …

Cyanobacteria are ancient prokaryotic photoautotrophs which are considered as ancestor of
chloroplast, having ability of oxygen evolution and are major biomass producers in both …

Proteins of the cryptochrome/DNA photolyase family (CPF) are phylogenetically related and
structurally conserved flavoproteins that perform various functions. DNA photolyases repair …

High‐altitude Andean lakes (HAAL) are a treasure chest for microbiological research in
South America. Their indigenous microbial communities are exposed to extremely high UV …

Exposure of DNA to ultraviolet (UV) light from the Sun or from other sources causes the
formation of harmful and carcinogenic crosslinks between adjacent pyrimidine nucleobases …
