Ligands: CL, GOL, NA Related: 5ltf, 5ltn, 5t2t Gene: L, KUE_IGS310002 (LCMV) Activity: RNA-directed RNA polymerase, with EC number 2.7.7.48 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [A0A059U382_9VIRU] RNA-dependent RNA polymerase which is responsible for replication and transcription of the viral RNA genome. During transcription, synthesizes 4 subgenomic RNAs, and assures their capping by a cap-snatching mechanism, in which cellular capped pre-mRNA are used to generate primers for viral transcription. The 3'-end of subgenomic mRNAs molecules are heterogeneous and not polyadenylated. The replicase function is to direct synthesis of antigenomic and genomic RNA which are encapsidated and non capped. As a consequence of the use of the same enzyme for both transcription and replication, these mechanisms need to be well coordinated. These processes may be regulated by proteins N and Z in a dose-dependent manner.[PIRNR:PIRNR000836] See Also RNA polymerase
