General annotation (Comments)

Function	Displays RNA-directed RNA polymerase, mRNA guanylyl transferase, mRNA (guanine-N(7)-)-methyltransferase and poly(A) synthetase activities. The viral mRNA guanylyl transferase displays a different biochemical reaction than the cellular enzyme. The template is composed of the viral RNA tightly encapsidated by the nucleoprotein (N). Functions either as transcriptase or as replicase. The transcriptase synthesizes subsequently six subgenomic RNAs, assuring their capping and polyadenylation by a stuttering mechanism. The replicase replicates the whole viral genome without recognizing the transcriptional signals By similarity.
Catalytic activity	Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). S-adenosyl-L-methionine + G(5')pppR-RNA = S-adenosyl-L-homocysteine + m(7)G(5')pppR-RNA.
Subcellular location	VirionPotential. CytoplasmBy similarity.
Sequence similarities	Belongs to the rhabdoviridae protein L family. Contains 1 RdRp catalytic domain.
