Human topoisomerase IIbeta in complex with DNA and etoposideHuman topoisomerase IIbeta in complex with DNA and etoposide
|
Crystal structure of a large fragment of human type II topoisomerases (TOP2) complexed to DNA and to the anticancer drug etoposide to reveal structural details of drug-induced stabilization of a cleavage complex[1].
The interplay between the , the , and the drug explains the structure-activity relations of etoposide derivatives and the molecular basis of drug-resistant mutations.
Also, at the we can see the , and both , and of the .
