[Enzymes of direct, excision, and corrected systems of repair of higher and lower organisms and their biological roles].
DNA repair is of paramount importance to protect the integrity of the cell genome. Over the last decade, DNA repair enzymes have been intensely studied owing to their role in mutagenesis, carcinogenesis, and aging. This led to discoveries of novel enzymes, protein factors as well as their intermolecular complexes involved in the repair process. Alternative pathways of cell response to the same type of damage were identified. Data on the tertiary structure of a number of enzymes and mechanisms of their molecular interaction were obtained. This paper is an overview of latest advances in the research of cell response to DNA damage via direct, base and nucleotide excision, and mismatch DNA repair.
