Method: X-ray diffraction, Resolution 1.7Å Ligands: EPE Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function POL_RSVSB Capsid protein p27: Self-associates to form the irregular polyhedron core composed of hexamers and pentamers, that encapsulates the genomic RNA-nucleocapsid complex. Assembles as a tube in vitro. Binds to inositol hexakisphosphate (IP6), which allows the assembly of the polyhedral capsid.[UniProtKB:P03322] Plays a role in the oligomerization of the Gag polyprotein and in the stabilization of the immature particle. Essential layering element during tube assembly. Allows the cooperative binging of Gag to the host plasma membrane.[UniProtKB:P03322] Binds strongly to viral nucleic acids and promotes their packaging (By similarity). Plays a role in the maturation-stabilization of the viral dimeric RNA via highly structured zinc-binding motifs (By similarity).[UniProtKB:P03322][UniProtKB:P0C776] The aspartyl protease mediates proteolytic cleavages of Gag and Gag-Pol polyproteins during or shortly after the release of the virion from the plasma membrane. Cleavages take place as an ordered, step-wise cascade to yield mature proteins. This process is called maturation. Displays maximal activity during the budding process just prior to particle release from the cell.[PROSITE-ProRule:PRU00275] Catalyzes viral DNA integration into the host chromosome, by performing a series of DNA cutting and joining reactions (PubMed:9218451). This recombination event is an essential step in the viral replication cycle. Has a strong preference for using the 3'-OH at the viral DNA end as a nucleophile.[UniProtKB:P03354] Evolutionary Conservation Check, as determined by ConSurfDB.
