The cleavage reaction occurs with the covalent attachment of an active-site tyrosine to the 3′ end of the broken strand; religation restores continuity to the DNA and releases the enzyme. During the cleaved state, relaxation of torsionally strained su

One of the main roles of the enzyme in the nucleus appears to be prevention of aberrant recombination by resolving double Holliday junction structures into non-crossover products; this role requires the formation of a complex with functional Bloom’s helicase as well as the

Once supercoils are suppressed, DNA breaks are rapidly resealed during the religation step of the Top1 reaction. The striking similarity between Top1-mediated religation and the strand transferase activity of various recombinases have su

This brief chapter gives an overview of the broad range of lesions that lead to the accumulation of cleavage complexes produced by DNA topoisomerases
