Exploring the Structure
Strand Transfer by Integrase (PDB entries 3os1 and 3os0)
Structures of PFV integrase with DNA have revealed the critical steps of the integration reaction. Click on the image to explore two structures: the complex just after the intasome captures the target DNA (PDB entry 3os1 ) and the complex after the strand transfer reaction (PDB entry 3os0 ).
Topics for Further Discussion
- You can use the Structure Comparison tool to compare the PFV integrase structures with the structures of different domains of HIV integrase.
- You can explore structures of several inhibitors with PFV and HIV integrase in the PDB.
