Function
NCAP_SENDO Encapsidates the genome in a ratio of one N per six ribonucleotides, protecting it from nucleases. The nucleocapsid (NC) has a helical structure with 13.07 N per turn. The encapsidated genomic RNA is termed the NC and serves as template for transcription and replication. Replication is dependent on intracellular concentration of newly synthesized N, termed N(0), which corresponds to the protein not associated with RNA. In contrast, when associated with RNA, it is termed N. During replication, encapsidation by N(0) is coupled to RNA synthesis and all replicative products are resistant to nucleases (By similarity).
