Chain 1,2,3,4   (POTD_SHIFL | P0AFL0)
molecular function
    GO:0019808    polyamine binding    Interacting selectively and non-covalently with polyamines, organic compounds containing two or more amino groups.
biological process
    GO:0015846    polyamine transport    The directed movement of polyamines, organic compounds containing two or more amino groups, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    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:0042597    periplasmic space    The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria).
