Recent advances in DNA catalysis

This is the authors' abstract. We don't add key points for this paper.

Studies of catalytically active DNA sequences have expanded considerably since the first artificial deoxyribozyme was identified in 1994. Nevertheless, the field is still quite young, and advances in both fundamental understanding and practical applications of deoxyribozymes are still developing. Deoxyribozymes that either cleave or ligate two RNA substrates have been most widely investigated, and this review describes recent advances in the fundamental studies and applications of these DNA enzymes. Deoxyribozymes with catalytic activities other than RNA ligation and cleavage are also increasingly pursued, and this review covers several key examples. © 2007 Wiley Periodicals, Inc.
