Asymmetric Unit(hide GO term definitions)
Chain A   (SAV_STRAV | P22629)
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
