Use of deoxyribozymes in RNA research.
Since their first identification by in vitro selection in 1994, deoxyribozymes have been developed to catalyze a variety of chemical reactions. The first DNA-catalyzed reaction was cleavage of a ribonucleotide linkage within an oligonucleotide substrate. In subsequent years, growing collections of deoxyribozymes have been developed for several reactions that have practical utility for RNA research. These deoxyribozymes are useful for site-specific RNA cleavage as well as ligation to form linear, branched, and lariat RNA products. An application related to RNA ligation is deoxyribozyme-catalyzed labeling of RNA (DECAL), which is used to attach a biophysical tag to a desired RNA sequence at a specific position. With current achievements and likely future developments, deoxyribozymes are a useful contributor to the toolbox of RNA research methods.
