Popis: Human Bloom’s syndrome (BLM) helicase has a role in DNA repair, and BLM deficiency in humans is associated with chromosomal abnormalities. Here the authors employ solution biophysical assays to show BLM maintains a balance for disruption and stabilization of oligonucleotide-based D-loops. Interaction with the Topoisomerase IIIalpha-RMI1-RMI2 complex orients the activity toward D-loop disruption.
