"Active" photoprotection: sunscreens with DNA repair enzymes [PDF]
Italian Journal of Dermatology and Venereology, 2017 Ultraviolet (UV) radiation exerts different harmful effects on human health, being the main etiological agent of certain skin cancers and photoaging. In this context, photoprotection, intended as a set of measures adopted to limit and prevent the effects of UV radiation, plays a critical role in avoiding undesired sunlight outcomes.

Current Opinion in Structural Biology, 1997
Recent crystallographic studies of DNA-repair enzymes have provided the structural basis for the recognition of damaged DNA. The results imply that flipping out of the base is a common and crucial event in DNA repair. Two classes of repair enzymes that recognize distinct types of damage may exist.

Current Protocols in Molecular Biology, 2008
AbstractIn vivo DNA damage impacts the genetic stability of an organism; therefore, multiple pathways utilizing a large number of enzymes have evolved to repair DNA damage. This unit focuses on enzymes involved in base excision repair (BER). The BER enzymes possessing Nâglycosylase activity can find and remove a wide variety of damaged bases in a sea ...

Tuberin regulates the DNA repair enzyme OGG1
American Journal of Physiology-Renal Physiology, 2008The tuberous sclerosis complex (TSC) is caused by defects in one of two tumor suppressor genes, TSC-1 or TSC-2. The TSC-2 gene encodes tuberin, a protein involved in the pathogenesis of kidney tumors, both angiomyolipomas and renal cell carcinomas. We investigated a potential role for tuberin in regulating a key DNA repair pathway.

Detection of DNA point mutations with DNA mismatch repair enzymes
Carcinogenesis, 1994We have developed a simple and reliable procedure to screen gene mutations using DNA mismatch repair (MR) specific mut Y enzyme of Escherichia coli and thymidine DNA glycosylase from HeLa cells. The mut Y enzyme cleaves A of G/A mismatches in DNA duplex and thymidine glycosylase cleaves T at G/T mismatches.

Aberrant activity of the DNA repair enzyme AlkB
Journal of Inorganic Biochemistry, 2004Escherichia coli AlkB is a DNA/RNA repair enzyme containing a mononuclear Fe(II) site that couples the oxidative decomposition of alpha-ketoglutarate (alphaKG) to the hydroxylation of 1-methyladenine or 3-methylcytosine lesions in DNA or RNA, resulting in release of formaldehyde and restoration of the normal bases.

DNA mismatch repair enzymes: Genetic defects and autoimmunity
Clinica Chimica Acta, 2015DNA mismatch repair (MMR) is one of the several DNA repair pathways conserved from bacteria to humans. The primary function of MMR is to eliminate the mismatch of base-base insertions and deletions that appear as a consequence of DNA polymerase errors at DNA synthesis.
