Observation of arenavirus nucleoprotein heptamer assembly
Abstract : Arenaviruses are enveloped viruses containing a segmented, negative and ambisense single‐stranded RNA genome wrapped with a nucleoprotein. The nucleoprotein is the most abundant viral protein in infected cells and plays a critical role in both replication/transcription and virion assembly. The nucleoprotein associates with RNA to form a ribonucleoprotein complex, and this implies self‐assembly while the exact structure of this polymer is not yet known. Here we report a measurement of the full length Mopeia virus NP by negative stain Transmission Electron Microscopy. We observed ribonucleoprotein complex particles with diameter 15 ± 1 nm as well as symmetric circular heptamers of the same diameter, consistent with previous observations.
