Disclosed herein are a crystal of a human TOPII (hTOPII)-DNA binary complex, the method for preparing the same and the use thereof. The hTOPII-DNA binary complex includes an hTOPII portion that contains an hTOPII core domain (hTOPII core ), and a synthetic double-stranded DNA in complex with the hTOPII portion. The synthetic double-stranded DNA has a first DNA strand comprising nucleotide positions 3 to 20 of the sequence of 5′-NNNCCGAGCNNNNGCTCGGNNN-3′ (SEQ ID NO: 1), wherein N is any one of adenine, thymine, cytosine, or guanine, and a second DNA strand complementary to the first DNA strand. |
