CC -!- FUNCTION: Responsible for RNA synthesis (replicase and transcriptase),
CC cap addition, and cap methylation (By similarity). Performs also the
CC polyadenylation of subgenomic mRNAs by a stuttering mechanism at a
CC slipery stop site present at the end of viral genes (By similarity).
CC The template is composed of the viral RNA tightly encapsidated by the
CC nucleoprotein (N) (By similarity). The viral polymerase binds to the
CC genomic RNA at the 3' leader promoter, thereby initiating either genome
CC replication or mRNA transcription. In the transcription mode, the
CC polymerase performs the sequential transcription of all mRNAs using a
CC termination-reinitiation mechanism responding to gene start and gene
CC end signals. Some polymerase disengage from the template at each gene
CC junction, resulting in a decreasing abundance of transcripts from the
CC 3' to the 5' end of the genome (By similarity). The first gene is the
CC most transcribed, and the last the least transcribed. The viral
CC phosphoprotein helps the polymerase to engage the N-RNA template and
CC acts as processivity factor. Polyribonucleotidyl transferase (PRNTase)
CC adds the cap structure when the nascent RNA chain length has reached
CC few nucleotides. Ribose 2'-O methylation of viral mRNA cap precedes and
CC facilitates subsequent guanine-N-7 methylation, both activities being
CC carried by the viral polymerase (By similarity). In the replication
CC mode, the polymerase replicates the whole viral genome without
CC recognizing the gene end transcriptional signals. The ability of the
CC polymerase to override the gene end signals as it is producing the
CC antigenome is probably due to replicative RNA becoming encapsidated
CC with nucleoprotein as it is synthesized (By similarity).
