RNA-dependent RNA polymerase (RdRp)

RNA-dependent RNA polymerase (RdRp) is an enzyme that catalyzes the replication of RNA from an RNA template. ("EC:2.7.7.48"https://www.brenda-enzymes.org/enzyme.php?ecno=2.7.7.48). All RNA viruses encode for this enzyme, except circular complementary RNA viruses (Kolmioviridae).


These enzymes are named RNA-rirected RNA polymerases (RDR) in cellular organisms.
