DNA-Directed RNA Polymerases MeSH Descriptor Data 2022


MeSH Heading
DNA-Directed RNA Polymerases
Tree Number(s)
D08.811.913.696.445.735.270
Unique ID
D012321
RDF Unique Identifier
http://id.nlm.nih.gov/mesh/D012321
Annotation
general or unspecified; prefer specifics
Scope Note
Enzymes that catalyze DNA template-directed extension of the 3'-end of an RNA strand one nucleotide at a time. They can initiate a chain de novo. In eukaryotes, three forms of the enzyme have been distinguished on the basis of sensitivity to alpha-amanitin, and the type of RNA synthesized. (From Enzyme Nomenclature, 1992).
