Literature

Crystal structures of B-form DNA-RNA chimers complexed with distamycin.

  • PubMed Abstract: 

    Two DNA-RNA chimers, complexed with DNA minor groove binding drugs, have been observed to adopt the B-form conformation for the first time. Thus, the RNA duplex may assume the B-DNA conformation when interacting with drugs, peptides or proteins.
