'''The pseudo-atomic structure of dengue immature virus'''
[https://www.uniprot.org/uniprot/A7TUD3_9FLAV A7TUD3_9FLAV] Component of the viral RNA replication complex that functions in virion assembly and antagonizes the host immune response.[ARBA:ARBA00024317]  Functions as a signal peptide for NS4B and is required for the interferon antagonism activity of the latter.[ARBA:ARBA00003504]  Serine protease subunit NS2B: Required cofactor for the serine protease function of NS3.[PROSITE-ProRule:PRU00859]

==Overview==
Many viruses go through a maturation step in the final stages of assembly before being transmitted to another host. The maturation process of flaviviruses is directed by the proteolytic cleavage of the precursor membrane protein (prM), turning inert virus into infectious particles. We have determined the 2.2 angstrom resolution crystal structure of a recombinant protein in which the dengue virus prM is linked to the envelope glycoprotein E. The structure represents the prM-E heterodimer and fits well into the cryo-electron microscopy density of immature virus at neutral pH. The pr peptide beta-barrel structure covers the fusion loop in E, preventing fusion with host cell membranes. The structure provides a basis for identifying the stages of its pH-directed conformational metamorphosis during maturation, ending with release of pr when budding from the host.
