DEFINITION

Classification: 435/91.31

Involving catalytic ribonucleic acid:

(under subclass 91.3) Processes wherein a ribonucleic acid (RNA) acting as an enzyme is involved as a reactant in, or as

a product of, a process of synthesizing a polynucleotide containing only ribonucleotide monomers.

(1) Note. Catalytic RNA is also called enzymatic RNA or ribozyme.

(2) Note. Catalytic RNA is RNA which can serve as an enzyme acting on other RNA molecules in vitro as a (a) dephosphorylase, (b) ribonucleotidyl-transferase, or (c) sequence-specific endoribonuclease.
