Architecture and regulation of negative-strand viral enzymatic machinery

Abstract excerpt

Negative-strand (NS) RNA viruses initiate infection with a unique polymerase complex that mediates both mRNA transcription and subsequent genomic RNA replication. For nearly all NS RNA viruses, distinct enzymatic domains catalyzing RNA polymerization and multiple steps of 5' mRNA cap formation are contained within a single large polymerase protein (L). While NS RNA viruses include a variety of emerging human and...
