Structure of ellipticine in complex with a 6-bp DNA
Overview
Ellipticine is a natural plant product that has been found to be a powerful anticancer drug. Although still unclear, its mechanism of action is considered to be mainly based on DNA intercalation and/or the inhibition of topoisomerase II. Many experimental data suggest an intercalation based on stacking interactions along the major base-pair axis, but alternative binding modes have been proposed, in particular for ellipticine derivatives. The 1.5 A resolution structure of ellipticine complexed to a 6 bp oligonucleotide unveils its mode of binding and enables a detailed analysis of the distorting effects of the drug on the DNA.
About this Structure
1Z3F is a Protein complex structure of sequences from [1]. Full crystallographic information is available from OCA.
