Structural and biochemical basis for DNA and RNA catalysis by human Topoisomerase 3β
The authors revealed novel roles of catalytic residues and divalent metal ions for hsTOP3B, the human RNA topoisomerase, and demonstrated the structural elements that kinetically modulate the DNA and RNA topoisomerase activities of TOP3B.

RNA-catalyzed evolution of catalytic RNA
An RNA polymerase ribozyme that was obtained by directed evolution can propagate a functional RNA through repeated rounds of replication and selection, thereby enabling Darwinian evolution. Earlier versions of the polymerase did not have sufficient copying fidelity to propagate functional information, but a new variant with improved fidelity can ...
