Only the catalytic palm subdomain, composed of a four-stranded antiparallel beta-sheet with two alpha-helices, is well conserved among all of these enzymes. The RNA-directed RNA polymerases in the first of the above superfamilies can be divided into the following three subgroups: By sequence By domain architecture.

First, the initiation step of RNA synthesis begins at or near the 3' end of the RNA template by means of a primer-independent de novo mechanism. Upon infection, the polyproteins encoded for the viral replication are translated. The domain organisation [ PMID:
