Asymmetric Unit(hide GO term definitions)
Chain A,B   (MXIC_SHIFL | Q04640)
molecular function
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
biological process
    GO:0050709    negative regulation of protein secretion    Any process that stops, prevents, or reduces the frequency, rate or extent of the controlled release of a protein from a cell.
    GO:0009405    pathogenesis    The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.
    GO:0009306    protein secretion    The controlled release of proteins from a cell.
    GO:0030254    protein secretion by the type III secretion system    The process in which proteins are transferred into the extracellular milieu or directly into host cells by the bacterial type III secretion system; secretion occurs in a continuous process without the distinct presence of periplasmic intermediates and does not involve proteolytic processing of secreted proteins.
    GO:0046903    secretion    The controlled release of a substance by a cell or a tissue.
    GO:0006810    transport    The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
cellular component
    GO:0009986    cell surface    The external part of the cell wall and/or plasma membrane.
    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.
    GO:0043657    host cell    A cell within a host organism. Includes the host plasma membrane and any external encapsulating structures such as the host cell wall and cell envelope.
    GO:0019867    outer membrane    The external membrane of Gram-negative bacteria or certain organelles such as mitochondria and chloroplasts; freely permeable to most ions and metabolites.
