1em9 is a 2 chain structure with sequence from Rous sarcoma virus - Prague C. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
GAG_RSVP Capsid protein p27 forms the spherical core of the virus that encapsulates the genomic RNA-nucleocapsid complex (By similarity). 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 (By similarity).
