Retroviral integration into nucleosomes through DNA looping and sliding along the histone octamer
Retroviral integrases catalyze the insertion of viral DNA into the host cell DNA and can use nucleosomes as substrates for integration. Here the authors present the 3.9 Å cryo-EM structure of prototype foamy virus integrase after strand transfer into nucleosomal DNA, which together with single-molec...

| Sumario: | Retroviral integrases catalyze the insertion of viral DNA into the host cell DNA and can use nucleosomes as substrates for integration. Here the authors present the 3.9 Å cryo-EM structure of prototype foamy virus integrase after strand transfer into nucleosomal DNA, which together with single-molecule FRET measurements provides evidence for a DNA looping and sliding mechanism of integrases. |
