MeSH Heading: RNA, Catalytic
Tree Number(s): D08.811.797; D13.444.735.790.199
Unique ID: D016337
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D016337
Scope Note: RNA that has catalytic activity. The catalytic RNA sequence folds to form a complex surface that can function as an enzyme in reactions with itself and other molecules. It may function even in the absence of protein. There are numerous examples of RNA species that are acted upon by catalytic RNA, however the scope of this enzyme class is not limited to a particular type of substrate.
Entry Term(s): Catalytic RNA; Ribozyme; Ribozymes
