Abstract.
DNA repair is a collection of several multienzyme, multistep processes keeping the cellular genome intact against genotoxic insults. One of these processes is base excision repair, which deals with the most ubiquitous lesions in DNA: oxidative base damage, alkylation, deamination, sites of base loss and single-strand breaks, etc. Individual enzymes acting in base excision repair have been identified. The recent years were marked with many advances in understanding of their structure and many interactions that make base excision repair a functional, versatile system. This review describes the current knowledge of structural biology and biochemistry of individual steps of base excision repair, several subpathways of the common base excision repair pathway, and interactions of the repair process with other cellular processes.
