    The structure of immature West Nile virus particles, propagated in the presence of ammonium chloride to block virus maturation in the low-pH environment of the trans-Golgi network, was determined by cryo-electron microscopy (cryo-EM). The structure of these particles was similar to that of immature West Nile virus particles found as a minor component of mature virus samples (naturally occurring immature particles [NOIPs]). The structures of mature infectious flaviviruses are radically different from those of the immature particles. The similarity of the ammonium chloride-treated particles and NOIPs suggests either that the NOIPs have not undergone any conformational change during maturation or that the conformational change is reversible. Comparison with the cryo-EM reconstruction of immature dengue virus established the locations of the N-linked glycosylation sites of these viruses, verifying the interpretation of the reconstructions of the immature flaviviruses.
