Here we report the cryoelectron microscopy (cryo-EM) structures of immature and mature DENV1 at 6- and 4.5-A resolution, respectively. The subnanometer-resolution maps allow accurate placement of all of the surface proteins. Although the immature and mature viruses showed vastly different surface protein organizations, the envelope protein transmembrane (E-TM) regions remain in similar positions. The pivotal role of the E-TM regions leads to the identification of the start and end positions of all surface proteins during maturation. Immature and mature dengue serotype 1 virus structures provide insight into the maturation process.,Kostyuchenko VA, Zhang Q, Tan JL, Ng TS, Lok SM J Virol. 2013 Jul;87(13):7700-7. doi: 10.1128/JVI.00197-13.
